Bill Kreutzmann held a conversation discussing his new book Deal last night in Los Angeles. Towards the end of the discussion, Kreutzmann surprised everyone by having a drum kit at the venue and a percussion kit set up next to him. To help fill the percussion kit, Kreutzmann called on Jason Hann who was in the audience to come on stage.

After the jam, which demonstrated a specific drum technique, Kreutzmann then pulled someone’s ticket number from a fishbowl and gave the winner a pair of tickets to Chicago, which the drummer paid for himself.

Kreutzmann’s book tour continues in Beaverton, OR tomorrow. Additionally, he will appear as a guest on Conan tonight.
