There’s a reason George Thorogood & the Destroyers’ discography includes more than half a dozen live albums. Their high-octane, sax-spiced, blues-rock works best in a concert setting, where audiences seem to energize Thorogood, and he interacts with them as well as he does with his guitar. The latest recorded evidence of that is on the new The Baddest Show on Earth: Greatest Hits Live. The title is a misnomer, since Thorogood hasn’t had any hits to speak of.
