King Gizzard and the Lizard Wizard gave fans the live debut of “Astroturf,” at the second of two shows in the underground amphitheater at The Caverns in Pelham, Tenn., June 2. It was the first time the band played live anything off their last album, Changes, released last October. That was one highlight in a show full of highlights, with inspired jamming and great song selection including four songs from the 2014 album I’m In Your Mind Fuzz to start the show and “K.G.L.W” to close it out loud.
