Great track! Saw the Mark 1 version of the Elektric Band with Scott Henderson, John Patitucci and Dave Weckl live years ago and they were kicking! Got to meet them personally as well and they the nicest guys you could ever hope to meet.
Who is the trombone player? I'm a trombonist. He's got technique, but I find him lacking as an improvisor who is a creative musician who composes on-the-fly and is able to make an evolving dynamic, integrated, and complete musical statement.
