Editor’s Note: Converse’s Rubber Tracks Live series at the Sinclair continued Tuesday evening for its second of five nights, putting some bounce in Cambridge’s step with performances by hometown electro-pop heroes Passion Pit, Los Angeles digital manipulators Baths, and Boston’s fast-rising electronic pop quartet Radclyffe Hall. Vanyaland’s Eddy Levia was lifted up 2015 and on hand to snap some shots of the best Tuesday night dance party this town has seen in some time. Rubber Tracks Live continues tonight with some metal flavor, starring genre titans Slayer and a pair of Massachusetts acts, Doomriders and Rozamov.
