Polyrhythmics, Kalu & the Electric Joint at the Mohawk indoor. The sprawling jams of Seattle groove collective Polyrhythmics will make you move, but hometown opener Kalu & the Electric Joint, the new project from Nigerian expat Kalu James, is also a big draw. The group’s latest release, ‘Time Undone,” simmers a slow burning dish of love and longing into a murky stew of muscular psychedelics, gut-bucket blues riffs and rootsy soul. $12-$15. Doors at 9 p.m. Saturday. 912 Red River St. mohawkaustin.com. — Deborah Sengupta Stith
