This Friday, The Uptown (1928 Telegraph Ave., Oakland) will host a free show featuring two local musicians who are coming into their own as solo artists. Cold Beat is the stage moniker of Hannah Lew, the bassist and co-songwriter of San Francisco indie-rock band Grass Widow. Although Lew wrote (in the liner notes of the EP she released last year) that she wrestles with paranoia and depression, her sound is nonetheless upbeat and surf-rock-like. The live band she’ll perform with at The Uptown will include guitarists Greer McGettrick (formerly of The Mallard) and Kyle King, as well as drummer Bianca Sparta of Erase Errata. Sharing the bill will be local hardcore veteran Tony Molina (of Caged Animal and Ovens), whose first solo album, 2013’s economical Dissed and Dismissed, is pure power-pop bliss. Oakland punk band Yi and self-described “adult contemporary” artist Cairo Pythian will open the show.
