?????? (Seatbelts), the name of the band, according to the fictional description given in the anime series Cowboy Bebop, derives from how the performers wear seatbelts to be safe while they play hardcore jam sessions. The band performed the whole soundtrack of the anime series Cowboy Bebop and produced a total of seven albums and one live DVD. Their style is very diverse and ranges from straightforward big band jazz, blues, acoustic ballads, hard rock, country, funk to electronic, hip-hop and experimental compositions/elements. Since the band was focused mostly on instrumental work, The Seatbelts had no lead singer. However, Steve Conte (from The Contes and Crown Jewels) and Mai Yamane participated and sang on many of their songs. The lyrics of these songs were written mainly by Tim Jensen and Yoko Kanno herself. Singers Soichiro Otsuka and Gabriela Robin (rumored to be a pseudonym for Kanno) were responsible for the backing vocals on songs such as "Blue". After a few years in hibernation, The Seatbelts regrouped in 2004 to perform the soundtrack for the second Cowboy Bebop video game, which is currently available in Japan. They all disbanded once they released the last album. Many of the members of The Seatbelts have also worked with Kanno and with each other on other projects as well, and some have even gone on to compose their own work. For example, guitarist Tsuneo Imahori also played guitar on the soundtracks for Ghost in the Shell: Stand Alone Complex and Wolf's Rain (both of which were composed by Kanno), as well as composing the soundtracks for Trigun and Gungrave.
