Friday night’s free music mixer continues with music from Jack O & the Sheiks, led by Jack “Oblivian” Yarber who, depending on who you ask, is either a rock legend or an absolute unknown. This dichotomy is well-understood by Memphis musicians, as underground “fame,” for all its rewards, has, with a few exceptions, been the ceiling for local acts for decades. And no one knows this dichotomy better than Yarber, who may be Memphis’ most influential active rock musician. The list of noteworthy bands Yarber has been a member of over the years is massive and includes Johnny Vomit & the Dry Heaves (a high school punk project that also featured future Squirrel Nut Zipper Jimbo Mathus), new-wavers the End, ’68 Comeback, Knaughty Knights, Tav Falco’s Panther Burns, the Compulsive Gamblers and the Oblivians. Come thirsty—the TapBox will be on hand with ten beers on tap, and Yippie Trippy food truck and vendor Texstyle Bags will be on site along with park games for all ages, including giant Jenga, cornhole, and more.
