The three members of this blues trio — Ian Moore, Johnny Moeller and Jesse Dayton — represent the last wave of the late Clifford Antone’s discoveries. The Austin-based blues club owner also famously mentored guitarists such Stevie Ray Vaughan, Jimmie Vaughan, Kim Wilson and Gary Clark, Jr. The Texas Headhunters will aim to keep his legacy alive when they perform tonight at 8 at the Beachland Ballroom.
