At last night’s sold-out Heartless Bastards show at Lincoln Hall, the inevitable happened: some dolt hollered “Freebird” during the quiet time between songs of the Bastards’ set. His hackneyed shout-out to the nine-minute Skynyrd romp elicited an immediate chorus of boos from what was, all things considered, a pretty mellow crowd, which had till then seemed content to soak up the chill high brought on by Erika Wennerstrom’s wailing. The band chuckled at the audience’s disgust, and bassist Jesse Ebaugh said something like, “I don’t think I’ve ever heard an entire audience boo one guy like that.”
