I skipped Robert Plant's recent show here in Charlotte. I just have a hard time paying over $40 to see anybody live. Maybe I'm cheap. I downloaded a show Plant played in Nashville on February 11th and I regret not going. I knew I would. I listened to the whole show the other night while reading and it's spectacular. Linked to below is one of the big reasons this show really entertained. It's the opening track, a rearranged version of Black Dog that is just stellar. It sounds like how Tom Waits would have rearranged the song.
