Which performers fizzled?
The Replacements, led by a noticeably disgruntled Paul Westerberg, played their first California show in over 20 years to a few hundred disinterested fans. Superchunk's set was woefully underattended as well, and the audience of April 12 headliner Muse was siphoned off by a concurrent performance by Skrillex that night.
Were there memorable covers?
Los Angeles-based R&B singer-songwriter Banks impressed with a shimmering cover of Aaliyah's "Are You That Somebody?" Blood Orange inspired a sprawling crowd -- which included U.K. singer Sam Smith -- with a mashup of OutKast's "Ms. Jackson," Del Rey's "Born to Die" and its own "Time Will Tell."
Which art project was the most eye-popping?
The piece de resistance of this year's art installations was "Escape Velocity" -- a 36-foot-tall, 40-foot-wide, 57-foot-long astronaut (No. 5 above) with a video-screen visor that slowly roamed the field. The star man's creator: Tyler Hanson of Poetic Kinetics -- the guy responsible for South by Southwest's Doritos vending machine and last year's most buzzed-about Coachella spectacle, the giant snail.
