The Seatbelts - Tank!
A 1998 theme for the anime series Cowboy Bebop was performed by the Japanese Blues & Jazz Band, The Seatbelts. Of course, it is one of best anime themes I listened to it. It has an extensive alto saxophone solo played by Masato Honda, as well as a fill part at the end. The song is a big band jazz piece in a Latin infused hard bop style with a rhythm section that combines a double bass and bongo drums.
