Friday was all about treating San Francisco like the beach town it ain't. SF Weekly Music Editor Jennifer Maerz watched Hot Rockin' Friday DJs spinning '70s punk and '80s psych at the Riptide before heading off to Mollusk for the surf shop's Geoff McFetridge art opening. At the surf shop-cum-gallery, DJ Trace Marshall kept the garage/surf tunes going. The latter was a cool, very casual little scene of kids, dogs and lots of hot, beachy-looking San Franciscans, Jennifer reports.

Our Ashley Harrell caught this month's SF installment of Mortified Friday night and joined the crowd at the Make-Out Room in snickering at adolescent tales from hell. Ashley, being Ashley, said she was "sort of hoping that one or two would bomb and show us the true definition of mortified. After all, the only thing more embarrassing then teenage thoughts is unintentionally bad comedy." Read her review over here.

Also on Friday, the Golding Collection of Rock Art snuck into the local Bonhams and Butterfields gallery on San Bruno Avenue and sat there all weekend long. This will probably be the first and last time such an extensive private collection of rock memorabilia will be in SF, the Bonhams press people inform us - mostly because the items will be auctioned off in NYC in May. The collection includes signed original works by local artists such as: Rick Griffin, Stanley Mouse, Alton Kelly, Victor Moscoso, Randy Tuten, David Singer, Dennis Larkins, Wes Wilson and Brits Michael English and Nigel Waymouth. From le press release:

Rock fans will delight in the memorable designs created to promote concerts and albums by bands such as The Grateful Dead, Jimi Hendrix, Bob Dylan, Pink Floyd, Aerosmith, The Doors, Jefferson Airplane, Bruce Springsteen, Eric Clapton, The Cult, The Sex Pistols, U2, Kiss, The Who, Alice Cooper, Quicksilver Messenger, Sly and the Family Stone, Ike and Tina Turner, Metallica and Guns and Roses, among others.

On Saturday, Jennifer Maerz observed the way the beautiful droning tones of Ascended Master filled the Catherine Clark Gallery -- which was hosting, very appropriately, a show that included a wall of album covers and a giant Led Zeppelin puzzle (pictured above). Ascended Master are less Zep, though, and more Krautrock, with the haunting voices of Catherine Brooks and Lauren Robertson making fast followers for this cult-riffing band. Dressed in matching white cloaks and black felt shawls, the group finished their set with a "ritual" -- placing more felt pieces on the ground and covering them with giant blue painted arms. From there, it was on to the Casanova, where the Weekly's own Dave Pehling kept the rock mood going with a DJ set including Zeppelin, Mars Volta and lots more of the loud and lumbering variety.

Our friends at sister paper LA Weekly blogged Coachella over the weekend and overheard some under-dressed lassies singing about the festival Rihanna-style. (As in. . ."Coach-ella-ella-ella Eh-eh.") We're just as grossed out as you. Read their coverage here. Also, Christopher Victorio shares his photos of MIA, Prince, Kate Nash, Death Cab, the Verve, Rilo Kiley and more with us. Flip through those here and spot the orgasm donor.

Happy Monday. --Janine Kahn
