Years ago, Garth Steel Klippert was a struggling musician living in San Francisco, back when the city was still a place where struggling musicians could afford to live. He rented an apartment above the infamous 6th Street Vietnamese dive Tu Lan, worked as a taxicab driver, and wrote odd little songs using a mishmash of instruments (Casio keyboard, saxophone, pot lids) and cobbled-together recordings he made while driving his cab late at night. (Music for Taxicabs was finally released on cassette three years ago.) Klippert eventually relocated to Portland, Oregon, where he currently resides and fronts the band Old Light. His new project is much more straightforward musically, but is still imbued with that gleefully unrestrained sense of imagination, a collage of shuffling and propulsive rhythms, funky guitar lines, unabashed rock riffs, rootsy Americana, and whatever else the four members fancy. The band set a goal of releasing five cassettes this year, and is apparently on track to do just that. In the meantime, Old Light will stop by the Bay Area this week for three shows: on Friday at The Chapel (777 Valencia St., San Francisco) with Thee Oh Sees, The Blind Shake, and OBN III’s; on Saturday at The Night Light (311 Broadway, Oakland) with BrEaKaRtS and My Life as a Dog; and on Sunday at The Make-Out Room (3225 22nd St., San Francisco) with Kelley Stoltz and Virgil Shaw.
