"Softly As In A Morning Sunrise"- Art Pepper
"Where Is the Next One Coming From"- Buddy Guy
"Strange Waters"- Bruce Cockburn
"There is Something On Your Mind"- Buddy Guy
"Bug In a Rug'- Steve Swallow
"Clamptown" - The Clash
I find this is a great way to work on making quick decisions (I would count only the first and last tune as ones I know particularly well) as well as being stylistically appropriate on each tune. I don't want to sound like Jazz drummer playing with the Clash anymore than I want to sound like a Blues drummer playing with Art Pepper. I like to think of it like acting. If someone's in a Tarantino film it's unlikely they would be speaking Shakespearian English. Play the gig, even if it's only you listening.
