El Perro Del Mar, with Taken By Trees. Triple Door, 216 Union St., 838-4333. 8 p.m. $18. El Perro Del Mar – the nom de plume of the blonde and delicate Swede Sarah Assbring – first floated into our consciousnesses back in 2006 with the tinny and twee “God Knows (You Gotta Give to Get).” Her latest record, Love Is Not Pop, is just as sweet and pretty and goes one further by introducing a new, previously untapped level of warmth and radiance. Lou Reed is cited as the main influential force behind the record, and there is indeed a moody aura hovering over these songs. Where her previous efforts were a bit glassy and timid, Assbring has transformed her music into something smoothly gelled together, surrendering to an expansive, openly emotional range of sounds. The songs are a wash of sleek keys and gently measured drums, topped off by Assbring’s slithering vocals, creating a mystic, grooving quality that has become her signature. ERIN K. THOMPSONDieselboy. Last Supper Club, 124 S. Washington St., 748-9975. 9 p.m. $10. Dieselboy prowls around in the dark, dank bowels of drum and bass, but his aesthetic isn’t medieval. Rather, his tracks grind and twist with a machinelike automation–a futuristic bent that recalls the apocalyptic scenarios of The Matrix and Terminator movies. In other words, these sounds don’t imprint rosy scenarios on the mind. Born Damian Higgins in Florida in 1972, Dieselboy is often credited as one of the primary movers and shakers of the jungle–and, later, drum and bass–movement in America. As if to further this reputation, in 2002, he founded the Human Imprint on the well-regarded indie label Systems Recordings. KEVIN CAPP
