Friday's music at Pitchfork opened direct from the wayback machine.
The first band on stage, Chicago's Outer Minds, drenched the soggy park with shimmering '60s psychedelic boogie. Singer-guitarist Zach Medearis, Vox organist Mary McKane and tambourine-confetti queen Gina Lira harmonize like the Mamas & the Papas, but the music is eight-cylinder garage-rock -- much wilder and reckless on stage than on record.
Medearis' Alex Chilton (Box Tops-era) bark and snaky Will Sergeant guitar lines literally vibrate in front of drummer Brian Costello's rolling fills and thundering drops. During "Until You're Dead," Costello was on his feet, pounding his toms like a musical Thor. Right on.
They were immediately followed on one of the main stages by the paisley sounds of the Olivia Tremor Control, a product of the Elephant 6 collective in the 1990s, re-formed in recent years (along with the reappearance of Jeff Mangum) with charter members Bill Doss and Will Cullen Hart. Their sunny '60s pop faced down Friday's looming clouds and included numerous horns.
