Last weekend Sensory Overload took a road trip to Chicago, where influential music site Pitchfork hosted its annual indie music showcase. An estimated crowd of 50,000 filled Union Park to watch hipster-friendly musicians perform under a relentless burning sun. Here's a breakdown of which bands thrived under duress and which ones wilted.

Last weekend Sensory Overload took a road trip to Chicago, where influential music site Pitchfork hosted its annual indie music showcase. An estimated crowd of 50,000 filled Union Park to watch hipster-friendly musicians perform under a relentless burning sun. Here's a breakdown of which bands thrived under duress and which ones wilted.

Most wildly inventive: tUnE-yArDs, who manage to be almost completely unlike other bands without sounding even a little bit forced. (Runner up: My beloved Dismemberment Plan, who still sound fresh 10 years after their final LP.)

Most pleasant surprise: G-Side. This Alabama rap crew swung from darkly emotional to coyly humorous without missing a beat, and they brought their own backup singers. (Runners up: Synth rockers Cut Copy and Sun Airway.)

Most anticipated: Fleet Foxes. Kids camped out without shade for hours to save a spot. Fortunately for them, Gen-Y's heirs to CSNY delivered, sounding humongous and note-perfect.

Most inoffensively derivative: Yuck, British kids offering a pleasant amalgamation of all the best American indie bands of the '90s. (Runner up: Wild Nothing, American kids offering a pleasant amalgamation of all the best British indie bands of the '80s.)

Most pretentious: Destroyer. Adding Dan Bejar's eccentric croak to Kenny G smooth jazz tripe doesn't magically redeem it. This is irony's point of no return. (Runners up: Cold Cave, who refused to lose their heavy leather jackets despite temperatures approaching triple digits, and Zola Jesus, the hipster Lady Gaga.)

Shockingly unpretentious: Animal Collective, who ditched their usual policy of focusing on new material and instead played a "hits"-heavy dance party. (Runner up: James Blake, who proved that he can do more than stare longingly.)

Best freakout: Ariel Pink; it's tough to tell if he's genuinely having a breakdown or not. (Runner up: Neurotic L.A. spazz-masters HEALTH.)

Screwed by scheduling: DJ Shadow. His light show didn't work very well considering the sun was still up. (Runner up: Shabazz Palaces, who were scheduled against Odd Future.)

Biggest letdown: Teenage rapscallions Odd Future, who delivered sufficient chaos but left me feeling like I was at the Gathering of the Juggalos.

As absolutely great as expected: Deerhunter, Guided By Voices (featuring Neko Case on backup vocals!), Kurt Vile and TV on the Radio.
