Pennywise

7 p.m. • Varsity Theater • 18-plus • $20-$35

One of the original, flagship bands that Bad Religion guitarist Brett Gurewitz signed to his punk label Epitaph in the early-'90s, Pennywise is one of the last of that era still standing, no thanks to the many Warped Tours it has done. The thrashy, often topical quartet from Hermosa Beach, Calif., is touring behind its 11th album, "Yesterdays," which saw original singer Jim Lindberg return to the fold. A Wilhelm Scream and Teenage Bottlerocket open. Chris Riemenschneider

The 9/16s Half B-Day Bash & Leprechaun Toss

9 p.m. • Icehouse • free

When most people share a birthday, they throw a joint party. When a group of six Twin Cities musicians have the same birthday, they form a band — at least in the case of the 9/16s, so-named for the date of their birth. This year, the group — which includes members of Alpha Consumer, "Wits" house band the Witnesses, the Honeydogs and Roma di Luna — is throwing a St. Patrick's Day bash and half-birthday party. They'll play their usual set of rock 'n' roll cover songs with a couple of country tunes thrown in. Opening acts include Tom Scott, who'll perform as a foul-mouthed rapping Irishman named Shady McGrumbles (more St. Patrick's Day events on page 20), Reverse Cowboy and DJ Sham Rock. (Note: No actual leprechauns will be tossed.) Jahna Peloquin
