The 2011 smash “Bax” shows off what’s best about Mosca’s idiosyncratic brand of postdubstep: The Numbers and Night Slugs artist takes advantage of compelling-but-never-distracting vocal snippets, supporting them with just the right amounts of funk and gloss, of grit and sheen. Fellow U.K. bassist Altered Natives has built up a prolific, confident body of work in the wake of broken beat and garage. Praveen Sharma of local bass duo Sepalcure appears tonight under his housier guise, Braille. With residents Rem Koolhaus, Contakt, Mayster, Space Jam and C-Sick.
