Performing music in a group is all about collaboration and communication. Look closely at this picture of the John Atkinson Trio, in performance on the last day of HE2007. JA is playing a solo, and both pianist Bob Reina and drummer Allen Perkins are listening and watching intently. In his comments after the number, Bob said that they had some differences of opinion about how to end the number, and resolving these differences required some give-and-take in the actual playing. Now that's jazz!
