John Vettese’s experimental/ambient music series “Still Life” returns this evening to the First Unitarian Church – Side Chapel. Tonight’s showcase features Fursaxa, Enumclaw and Helena Espvall (from Espers). So if the frenetic chaos of Liberty Fest and PiLam’s Human BBQ isn’t quite your cup of tea, then you know where to go for a calmer evening of contemplative music. First Unitarian Church – Side Chapel, 2125 Chestnut St., 9pm, $8, All Ages – H.M. Kauffman
