• Roger Waters brought the mega-spectacle of his The Wall live show to AT&T Park, and took a stand for bleeding hearts and artists everywhere. In what has to be the best Pink Floyd tour ever, Rogers uses The Wall to denounce militarism and social control in all its pernicious forms, and performs some amazing songs in the process. We'll never forget it.
• In its Barbary Coast and Beyond performance, the S.F. Symphony brought banjos and video projections onstage to explore the high-, low-, and no-brow of the city's cultural past, as music director Michael Tilson Thomas put it. The multimedia retrospective was highly unusual — and a total success.
• Can you do the J12? This latest Bay Area hip-hop dance craze is super easy: Just sway your hips in a wide circle, and swing your left arm. Make sure to listen to "Slow Down" by the Team while you do it. And if you think you're really good, you could always enter KMEL's J12 contest.
• It was supposed to be held in the lots around AT&T Park, but the two-day I Love This City electronic megafestival got moved to Shoreline Amphitheatre in Mountain View. While that means there are some lower-priced tickets available, the fest will no longer be the San Francisco-centric party we were hoping for. And now the name just seems weird.
• The Brian Jonestown Massacre returned to the Fillmore on Saturday. But even now that he's sober, the attitude of frontman Anton Newcombe poisoned the show. He started out friendly, then went on a rant and began cussing people at the venue out, distracting fans from the music.
• Don't expect to see lots more big shows at Nob Hill Masonic Center: Live Nation wants to hold more there, but members of the Nob Hill Association don't want more concertgoers in their posh 'hood. They're fighting a new deal with the promoter to do 54 shows a year in the 3,500-seat hall.
