Welcome to Part II of our South by Southwest coverage, where our tireless concert goer braves five straight days of live rock ‘n roll. First we tackled the headliners. Here, it’s showcase time.

Official SXSW showcases took place each night, in six hourly slots from 8 pm to 1 am. So much music, so little time, so many choices. Here’s some of the highlights.

Tristen, The Phoenix

Wednesday night featured an 8 pm set from Tristen at The Phoenix. The Nashville singer/songwriter/guitarist deals out an infectious brand of pop rock with a rootsy base and strong melodic hooks. She’s got a great voice that at times recalls Jenny Lewis from Rilo Kiley. But “The Ringerâ€� had more of a retro pop vibe a la She and Him, while “New Punching Bagâ€� had a gloriously bouncy guitar shimmer.

Fifth Nation, The Tap Room

One of the most unique aspects/perks of SXSW is the potential to discover a great new band you’ve never heard of when your ear just happens to catch a compelling sound from the street. So it was after Tristen’s set when a soaring voice from a nearby rooftop caught our ear. A quick scramble up the stairs at the Tap Room revealed Fifth Nation, out of Brooklyn. Singer/guitarist King Julia has a voice with some of the soul undertones of a Lauren Hill or Erykah Badu, but she puts it in more of a rock context. She and drummer/keyboardist Music Read are just a duo, but create a full sound. Just catching the last 10 minutes of the set revealed this pair as a talent to keep an eye on.

Immortal Technique, Mohawk Patio

Legendary underground hip-hop artist Immortal Technique played to a packed house at the Mohawk Patio at 11 pm. He certainly delivered a high-energy set, although it seemed a bit heavy on plain old anger and a bit short on the radical, left-wing political lyrics that he’s famous for, such as a tune about 9/11 being an inside job. His message would also probably come across stronger if he had a band instead of just a DJ and four hype men.

Nico’s Gun, Annie’s West

We spent the whole evening at the ACL Live venue on Thursday, but Widespread Panic’s set was over around 12:30 am, so there was still one more showcase to be caught in the 1 am slot. The perfect aftershow party was not far away as Nico’s Gun out of Philadelphia threw down a raucous set at Annie’s West on Sixth Street. The funky rock quartet got the party going immediately as girls were dancing onstage during the first song! The band sustained that high energy level throughout their set, mixing some psychedelic qualities in with the funk to keep the Spreadheads dancing the whole time.

Liz Phair, IFC House

Friday night saw ’90s indie-alternative darling Liz Phair was in high demand rocking the intimate IFC House. Phair is 43 now, but she’s a testament to human evolution because she doesn’t look or sound a day over 28. She hit the stage rocking a short mini-skirt and her classic power pop jam “Supernova,â€� which elated the small but packed room. It’s a strange venue since the concert area is so tiny, yet there are also widescreens showing the performance in the lobby where free drinks and pretzels were being served. Phair ran through a crowd-pleasing greatest hits set, but also tossed in a great new song and then closed it out in triumphant style with her classic “Fuck and Run.â€�

It was tempting to try and catch the psychedelic rock of Austin’s own Black Angels in the midnight hour, but the Cedar Street Courtyard was a total crowd scene as Jeff Spicoli would say, so it became more appealing to check out Toubab Krewe at Copa. The Asheville jamband drew a festive audience and delivered the goods with some uplifting melodic jams that had the Copa crowd moving and grooving.

It was also tempting to catch Sharon Van Etten at the Central Presbyterian Church at 8:30 pm on Saturday, as her sweet voice would surely sound extra fine with those sensational acoustics. But the Bright Eyes set at Auditorium Shores was just too good to leave at that point. Afterward, it was over to the Belmont on West Sixth, a great little courtyard venue where Nico’s Gun were playing again. The funk quartet were worth seeing again, especially with the improved acoustics and great light show of the classy outdoor venue. It was another great set as the boys showed themselves as a band to watch on the jam rock and festival scene.

Dawes, Lustre Pearl

There were lots of attractive options in the midnight hour with Austin power trio Ume (above) at Skinny’s Ballroom, as well as Texican rockers Los Lonely Boys at the Phoenix. But with the Band’s Robbie Robertson having recently tabbed Dawes to be his new backing band, catching them at Lustre Pearl seemed like the way to go. It didn’t take long to see why Robertson fell in love with the band; They’ve got a compelling vintage folk rock sound coming out of LA’s Laurel Canyon scene. They also have great chemistry, thanks to bassist Wylie Gelber, who was just flat-out amazing. His warm liquid bass runs showed a total mastery of the instrument and boosted every tune higher.

Coming up next: the day party sets and conference panels

The 2010 Austin City Limits Music Festival continued to make the three-day event’s case as one of the best festivals on the planet. It went off with nary a hitch, and in fact, this year’s edition may have had the festival’s best weather yet. There was no dust, no rain to turn Zilker Park into a giant mud pit (like last year) and the high temperature never reached 90. The sunny afternoons were still plenty hot, but the evenings were downright balmy. Some local fans bitched about the overall lineup when it was first announced, but there truly was something for everyone in the festival’s ever-eclectic lineup. The festival once again sold out well in advance, and again proved to be one of the best weekends of the year for any serious music fan.

The tasty local cuisine available at ACL is topped only by New Orleans’ Jazzfest (although unfortunately neither fest seems willing to bring in local beer), and the football tent returned to enable sports fans to get a fix in between music sets. There were only a handful of occasions where the crowd scene proved overly massive and hard to navigate. Overall, it was three days of near-utopian rock ‘n’ roll bliss. If the word “groovyâ€� is overused in this review, it’s only because there were indeed so many such moments. The biggest problem was choosing between competing bands in a series of mind-bending conflicts: Silversun Pickups vs Broken Bells, Monsters of Folk vs LCD Soundsystem, Phish vs The Strokes, The Flaming Lips vs Band of Horses, and the terrible three-way Friday night dilemma of Sonic Youth vs Robert Randolph & the Family Band vs Ryan Bingham & the Dead Horses. Cloning technology can’t arrive soon enough.

Friday, October 8

Those Darlins, Austin Ventures Stage
This upbeat Tennessee quartet featured a relatively unique mix of country punk and garage rock to create a fun vibe. Singer/guitarist Jessi Darlin’s gritty voice recalled Courtney Love at times in its ragged splendor, but with more of a country flavor. “Red Light Loveâ€� saw the band at its best on a fuzzy, melodic rocker about the combination of good love and good music.

Blues Traveler, AMD Stage
It seemed like a flashback to the mid-’90s when Blues Traveler drew a huge crowd to the festival’s second largest stage to really get ACL going. It’s been great to see the band able to persevere through the tragic death of original bassist Bobby Sheehan and the health problems of singer/harmonica ace John Popper, who is now fit and sounding great as ever. Underrated guitarist Chan Kinchla always keeps things groovy on his PRS guitar and his brother Tad fits right in on bass. A cover of Radiohead’s “Creepâ€� was a surprise crowd pleaser, followed shortly thereafter with the band’s 1994 hit “Run-Around.â€� But the clear peak of the set – and one of the top highlights of the entire weekend – occurred when the band welcomed 15-year-old violinist Ruby Jane to sit in on “Mulling It Over.â€� Jane, who would play her own set on Sunday morning, proved to be a dynamic prodigy. She immediately accented the hard rocking tune in tasteful fashion, before teaming with Popper for a superb violin-harmonica duel that won the weekend’s first huge cheer.

The Black Keys, AMD Stage
The Akron, Ohio-based blues rock duo hit the stage at 4 pm in front of a massive crowd that made it tough for anyone arriving late to get close enough to enjoy. There were so many people camped out in their lawn chairs that the entire area became quite difficult to navigate. The Black Keys are clearly surging in popularity – they played to about 10,000 fans at the 2008 Outside Lands Festival in San Francisco, but this crowd was at least three times as large. I finally gave up and decided I’d rather check out the next band on the intimate BMI stage.
