Recorded by the group Chicago, this signature hit has gone on to become a rock classic. Paul Murtha's easy arrangement is playable with very limited rehearsal time, but still has an authentic and hard-driving feel. Included are optional solos or solis for any sax and any brass instrument. Suggested solos and scale/chord sheets in all keys are included. Playable with optional reduced or expanded instrumentations, it also includes a CD. Highly recommended!
