Tomahawk, the experimental rock supergroup led by Mike Patton, and the Melvins, the long-running Pacific Northwest band credited with shaping sludge and doom rock, play a co-headlining concert at the Riviera Theatre in Chicago. The show pairs Tomahawk’s genre-blending, avant-garde songwriting with the Melvins’ heavy, riff-driven approach, offering an intense live experience for fans of alternative, noise, and heavy rock.
