During downtime at this past weekend's Rothbury Festival in Michigan, SPIN correspondent Daniel Cassanova talked to some of the best acts there -- Gregg Gillis of Girl Talk, California indie-folk band Wendy Darling, electronica duo Pretty Lights, and Lyrics Born of the hip-hop collective Quannum All Stars.

It's only fitting that a concert series based in Williamsburg, Brooklyn -- hipsterdom's Plymouth Rock -- has assembled a lineup stocked with indie faves galore.

On Bonnaroo's third day of action, artists continued to visit with SPIN's Peter Gaston at the Budweiser Troo Music Lounge for interviews and fan questions.

Starting the afternoon off were Chuck Garvey and Rob Derhak of Western NY rockers moe., who were just beginning a long day that culminated in their 1-4 A.M. performance at the festival's This Tent.

"Girl Talk: I'm Not a DJ" flashed the giant video screens next to the stage at NYC's Hiro Ballroom Thursday night. And yet, there was GT's Gregg Gillis front and center, surrounded by a crush of sweaty twenty-somethings dancing to his dizzying mash-ups of Top 40 radio and kitschy classics.

With a mind-bending mash-up of underground gems, top 40 hits, and vintage classics, Pittsburgh's Gregg Gillis, a.k.a. Girl Talk, always gets the party started. And Saturday night's show -- the first in a sold-out three-night stand at Manhattan's Terminal 5 -- was certainly no exception as confetti flew and fans danced onstage.

It's a stifling July day in Pittsburgh, and Gregg Gillis, a.k.a. Girl Talk, is dressed accordingly: soccer shorts, white T-shirt, and a bandanna around his forehead. After releasing 2006's Night Ripper, the pop-savvy cut-and-paster quit his biomedical engineer job and went from playing tiny underground venues to chaotic dance parties around the globe.
