1) Clowns, elephants, tigers, horses, hoops, trapeze artists, acrobats, unicyclists, a ringmaster, and three rings add up to the “Greatest Show on Earth.” Ringling Bros. and Barnum & Bailey Circus have pulled into town, performing the latest version of their classic circus, “Built to Amaze!” It’ll be in town through Sunday. 7 p.m. Consol Energy Center, 1001 Fifth Ave., Uptown.
2) Pittsburgh rock royalty Norm Nardini has said many times he’s a “rock ‘n roll lifer.” His passion and energy drive him in his continuing mission to rock for the people. Nardini has played with top rockers Jon Bon Jovi, Ted Nugent, Big Mama Thornton, Aerosmith, Kansas, and others. He’s also fronted his own band, Norm Nardini and the Tigers. Nardini once told someone in New York City that he was from Pittsburgh, and the man replied, “Pittsburgh? Where’s that, Pennysltucky?” Norm’s from a rockin’ family, too; brother Art is the bassist for Joe Grushecky & the Houserockers. Catch Norm Nardini in concert with his talented band tonight at Jergel’s Rhythm Grille. 8 p.m. No cover. 285 Northgate Dr., Warrendale.
3) Student-directed plays at Carnegie Mellon’s School of Drama are FREE to the public; just visit the box office on the day of the performance to obtain a ticket.
