• Derrick May proved Detroit techno is still very much alive with a riveting set at Public Works. Putting lots of mileage on the club's EQs, he kept the floor moving past 3 a.m. We thought we might fall over from exhaustion, but then May roped us back in with another song.
• So you thought Converse only sells shoes? The company also plans to let local musicians record for free at a pop-up studio in S.F. this month. Acts keep all the rights to their work, and don't need to play any particular genre to get in. No word on whether the studio grants come with a free pair of Chucks, but apply before May 20 if you want to find out.
• You don't need to fear hypnotic, 10-minute guitar workouts when Kurt Vile is playing them. The Philly rocker sold out the Independent and showed that all his gorgeous haze just goes to make the variations more interesting. It was impossible not to get swept up in his lovely sonics.
• After so much hype, Napa's new Bottle Rock Music Festival proved a disappointment. The bands on Friday felt like a sideshow for all the beer-swilling and cash-dropping, and their sets were way too long anyway. By the end there were precious few surprises, and not many memorable moments, either.
• Black Pancake Records in the Lower Haight is closing its doors this weekend. Founded as Tweekin Records in 1992, the store moved to the corner of Haight and Steiner in 2010 and became Black Pancake. Until it closes Sunday, new records are 30 percent off, and used records are discounted by half.
• Watch out: Kanye West's God complex has returned with a vengeance. Dude took to the stage at a posh New York gala and declared, "I am a god!" Okay, so it's the name of a new song of his. But still, it can't be a good sign.
