In 2005, a decade after Jerry Garcia’s death, his longtime organist Melvin Seals launched JGB Band as a tribute act that jammed on well-known songs from their fifteen-year collaboration in the Jerry Garcia Band, plus Seals’ own compositions. Melvin Seals & JGB play for the dance and jam crowd Friday at Ashkenaz in an all-ages show. Along with Seals, the band features singer-guitarist Stu Allen, bassist Marty Holland, and drummer Sam Howard. Opening is Jolly Gibsons, a new act featuring New Orleans and jazz-R&B pianist Jennifer Jolly and guitarist Steve Gibson. 9:30 p.m., $17 advance/$20 door. 510-525-5054 or Ashkenaz.com
