HI-YAH! is the sound of mayhem – of flying fists and roundhouse kicks, ninja stars and fighting sticks. Cowboy Bebop isn't exactly that way, although it can be kinetic, and neither is its sister anime, Samurai Champloo. Although they create these interesting impressions with some pretty gorgeous art too boot. Cowboy Bebop also is a noted anime for injecting quite a bit of jazz into their mix. A friend of mine last night gave me a link to an interesting mix of, I think it's triphop or hiphop. I don't know, but it has a nice vibe, and pretty mellow so you can do task while listening to it. Check it out.
