The Black Crowes--still a little Led Zeppelin and a lot Lynyrd Skynyrd--have embarked on their Say Goodnight to the Bad Guys Tour, in which they play two 90-minute sets, one electric and one acoustic. 2010's Croweology spans 20 years of band history in all-acoustic format, covering radio favorites such as "She Talks to Angels" and barn-burners such as "Sister Luck" with homespun intimacy. In case you're waffling, the Black Crowes insist that this is their last tour before another indefinite band hiatus. Drama queens.
