• Stern Grove Fest announced its lineup of free concerts for Summer '13, and the list includes Nor-Cal hip-hop group Deltron 3030, soul-rock legend Shuggie Otis, the S.F. Symphony, and more. The Sunday afternoon shows begin June 16, at 2 p.m., but you probably want to show up early.
• Pianist Jason Moran explored the possibilities of the new SFJAZZ Center by performing live alongside 10 skateboarders shredding a mini-ramp right in front of the crowd. The show illustrated that jazz and skateboarding aren't actually strange bedfellows – both stitch simple, improvised tricks into long, evocative performances.
• May 4 was Jawbreaker Day – a holiday when obsessive fans of the defunct S.F. punk band come together to drink excessively, smoke cigarettes, and mourn the loss of this excellent trio. We celebrated with a playlist of the 10 Jawbreaker songs you must hear every May 4.
• At $28 per song, based on the price of our press ticket, the Rolling Stones' Oakland show had a lot to live up to – and it didn't make it. Keith Richards and Charlie Watts never quite clicked, and even the relentless Mick Jagger couldn't rescue them. The setlist was incredible, and so was Tom Waits' surprise appearance. But Sunday showed that the idea of the Stones at 50 might be better than the actual thing.
• After Bob Weir collapsed onstage April 25, his band Furthur was forced to cancel its appearance this Thursday at BottleRock Napa Valley. Weir and fellow former Dead member Phil Lesh will return to the tour circuit in July, but the Napa festival hasn't announced a replacement headliner.
• R.I.P. Slayer guitarist and songwriter Jeff Hanneman, who helped define what we know as metal with his fearsome riffs and atonal soloing. The writer of such classics as "Angel of Death" died of liver failure at an L.A.-area hospital. He was 49.
