The two-day Hemisfair music festival that promoters unveiled last month and trumpeted as a resurrection of San Antonio’s decades-gone La Semana Alegre concert series now has a lineup. Scheduled for April 25-26, the Fiesta-timed bash will feature headliners including North Texas post-grunge band Toadies, Grammy-winning Latin fusion act Ozomatli, LA indie rockers The Red Pears and San Antonio alt-rock trio Girl in a Coma. In a nod to La Semana shows of old, the bill will include two local favorites from the ’80s and ’90s: proto-metal cult heroes Legs Diamond and “nuevo wavo” Tex-Mex rocker Joe “King” Carrasco.
