I walked out of a Little Feat concert back in the day.
I was really into George Thorogood at the time and he was opening for Little Feat. I'd never really heard of Little Feat and after Thorogood's straight ahead blues/rock, the bizarre mixture of rock, country, latin, and funk was just too much. Me and my friends walked.
Years later, I came to appreciate the bizarre mixture of styles and have been kicking myself ever since.
RIP!
