Zebra never quite reached the popularity of their Atlantic Records brethren AC/DC, Yes, and Led Zeppelin and in the past, have been relegated to Led Zeppelin knock-off status. Fuck the know-nothings. Demanding fans have been keeping this metal band busy since Zebra’s 1983 debut, prompting the band to release new albums and continue playing shows well into their 37-year career. They play at B.B. King Blues Club Dec. 27, 7 p.m., $28, all ages. thedoor.com.
