SERIOUS BANJO: Funnyman Steve Martin is known for such classics as “The Jerk,” “The Three Amigos,” and the existential drama “Grand Canyon,” but he also has a knack for playing the banjo. Martin and The Steep Canyon Rangers stop by the Cadillac Palace in support of Martin’s new album, “The Crow: New Songs For The Five-String Banjo.” 151 W. Randolph St.; Loop. 8 p.m. All ages.
FEED ME, SEYMOUR: And speaking of Steve Martin, the Hideout hosts a production of the musical comedy “Little Shop Of Horrors.” So forget “Jersey Boys,” grab a PBR, and unwind to a singing plant. 1354 W. Wabansia Ave.; Noble Square. 8 p.m. $15. 21 and older.
RUN AWAY AND JOIN THE CAT CIRCUS: That’s right. The cat circus. The Amazing Acro-Cats of Chicago put on a Halloween-themed show at the Viaduct Theater, where they’ll ride skateboards and roll some pumpkins. 3111 N. Western Ave.; Roscoe Village. 7 p.m. $12.
