Since the late 1970s, George Thorogood and the Destroyers have been churning out a brawny assimilation of the blues genre typical of white bar bands after the British Invasion. The bandanna may now conceal the hairline, but there’s no hiding the influence of John Lee Hooker, Bo Diddley and Hound Dog Taylor when “Bad to the Bone” is dusted off yet again on Thursday, April 7, at the Uptown Theatre. 1350 Third St., Napa. 8pm. $40–$50. 707.259.0333.
