There are lots of swing charts based on blues changes. This one is in a class of its own. An attention-grabbing intro leads to the unison ensemble melody, followed by a few choruses where all sections trade off with the lead line. The open solo section can feature any instrument with suggested solos included. After a solo spot for drums things get even more interesting and fun! The dynamic level comes way down and your bass player gets to shine with some tasty written solo licks. The final ensemble chorus builds to a shout section that really - SHOUTS! A very impressive, effective and playable chart!
