There's raw vinyl in Eureka for the starved polymer gourmand. Phatsy Kline's features Marjo Lak spinning black gold on her decks at 7 p.m. for the weekly Laidback Lounge and over at Siren's Song at 8 p.m., the 33 and a third Thursday brings old skool sounds curated by DJs Goldylocks and Fade. As always, both events are free as a bird.
