Evanston, Ill., home base to Northwestern University, produced high school friends going by the name Manwolves long before they became a band. The sextet bonded over rap and exchanged stories about the music in their parents’ collections, soon forming a low-maintenance jazz-rap act under the name everyone already knew them by. Still without an album, this regional tour testifies to their raw talent and that of openers the Slaps, an indie rock outfit also from Chicago.
