Phat and Sassy opens with eight bars of Gene Krupa-style tom-toms and places this chart solidly in the hard-swinging big-band genre of Benny Goodman and Lionel Hampton. The saxes charge in with the melody which is soon traded back and forth with the brass sections. Tenor sax, trumpet, and drum solos over accessible changes follow, leading to a trombone section riff that builds through the ensemble. The sax section then takes over for a swinging soli before returning to a shout chorus and ending. This chart is a real flag-waver that teaches the fundamentals of the swing style along with an historical perspective. A super chart that is highly recommended!
