Best Caffeine Substitute at Midnight: Passion Pit

Apart from taking in all the awesome bands at this year's Bonnaroo festival, SPIN.com's also been gabbing with some of this year's hottest performers, both at our campsite and at the Troo Music Stage.

Stripping never goes out of fashion. And this week's hot music video from Brooklyn duo Matt and Kim makes that point with style. Meanwhile, Boston indie darlings Passion Pit's clip treats fans to a psychedelic extravaganza. Watch both below, then let us know what you think in the comments section.

More performers have been added to the lineup for this June's Bonnaroo Music and Arts Festival. Hip-hop vanguards Public Enemy and West African duo Amadou & Mariam have joined the roster, along with indie rock up-and-comers White Rabbits and Passion Pit, underground rapper Murs, and roots-rocker Ani DiFranco.

Dark romantic legends Echo & the Bunnymen are set to headline SPIN's annual Friday afternoon soiree at Stubb's BBQ during next month's South by Southwest music conference in Austin, Texas.

"Pain in the ass!" rasps Michael Angelakos as he struggles to heave a Fender Rhodes keyboard onto the stage of Los Angeles' Henry Fonda Theater. Angelakos, 21, is the benevolent dictator of synth poppers Passion Pit, and his band are soundchecking for their slot opening for French electro sensation Yelle.
