It's unlikely there's a frat house in the Western world that hasn't blasted Dave Matthews' world- and jazz-flavored pop through its party-size speakers. Along with Eddie Vedder, Matthews changed the way mainstream musicians pronounce the letter "R" (more like a pirate, less like an emotional diva), and he's been touring virtually nonstop for the past decade. Dave's last studio album, 2003's Some Devil, found the troubadour toning things down a bit and preferring the slow strum to the extended jam his band usually purveys. But an outside date in the summertime means only one thing: DMB and its upbeat instrumentals echoing off thousands of joyful, bouncing fans, who will feel especially great knowing that this particular show benefits, according to the band's Web site, "Bay Area community charities addressing issues of homelessness among single adults, youth and families, pediatric AIDS and other terminal childhood maladies, Bay Area park improvement and music education resources." The rock goes down at noon on Sunday, Sept. 12, at the Polo Fields in Golden Gate Park; go to www.dmband.com for more info.
