This week for What Where When-sday, we discuss the Courtyard Concert series at the Nashville Public Library’s downtown location. It’s happening every Tuesday from Sept. 3 to Oct. 22.

Get your week started tonight with Steve Earle at the Ryman. Then, this Friday at Geodis Park, Green Day performs with the Linda Lindas opening the show. On Saturday, we’ve got WNXP’s second annual 91 Day taking place at The Blue Room from noon until 7 p.m. — with local vendors and music starting at 1, including Nashville artists BEAN., Sugadaisy, Bats, and Mike Floss.

Later on Saturday, King Gizzard and the Lizard Wizard play at Ascend Amphitheater, and at the same venue on Sunday, WNXP Nashville Artist of the Month Cage the Elephant performs. Wrap up the weekend with Childish Gambino at Bridgestone Arena.
