Rush is a song from Cowboy Bebop and performed by the Seatbelts.

Much like the anime's opening theme Tank!, it is an instrumental big band jazz piece that goes for a fast pace rhythm with a mix of bongo drums, double bass, alto sax, and in this case, guitar.

It is included on the Cowboy Bebop soundtrack. An alternative version in a different key titled N.Y. Rush is also featured on Blue with added electric piano. This song is most notably heard during fight scenes, particularly in the first session Astroid Blues between Spike and Asimov.
