Cowboy Bebop (カウボーイビバップ) is a 1998 Japanese anime series developed by Sunrise. It featured a production team led by director Shinichirō Watanabe. The twenty-six episodes ("sessions") of the series comprise a complete storyline set in the year 2071.
It follows the adventures, misadventures and tragedies of a bounty hunter crew travelling on the Bebop, their starship. Cowboy Bebop also explores philosophical concepts including existentialism, loneliness, and the influence of the past (Vault Magazine).
It was accompanied by a number of soundtrack albums composed by Yoko Kanno and The Seatbelts, a diverse band Kanno formed specifically to create the music for the series, with a principal focus in jazz. Easily one of the best soundtracks for a T.V. series, Cowboy Bebop's music is as timeless as the show itself.
