CAA: Christian Anime Alliance

Yoko Kanno is my favorite anime composer, so I was wondering which anime title containing her music has her best work? I personally liked Wolf's Rain best.

Cowboy Bebop I'd say. 5 CD's of Yoko goodness with jazz, rock, pop, ethnic, and any combination of those.

A tie between Cowboy Bebop and Ghost in the Shell: SAC.

Cowboy Bebop. Did you really need to ask?

Well a lot of it really has to do with your own personal taste. I've noticed that as opposed to sticking to one style like, for example, Kaoru Wada (Inu Yasha, Ninja Scroll, Gilgamesh), most of the time Kanno's music varies depending on the series. For example, Cowboy Bebop has the best jazz ever to be put into an anime, but Escaflowne is known for its classical music. Possibly the three most debated soundtracks (in the question of what Kanno's best work is) are some of her earlier works: Cowboy Bebop, Escaflowne, and Macross Plus.

If you want to get a nice variety and get an idea of what her music's like, try Stand Alone Complex. Bebop has some variation as well, but this is much more the case in SAC, and the latter is also shorter and, being available in the US, much easier and cheaper to get.

Also Wolf's Rain was quite good. It's not as good as some of her other work, but for some lighter music, it's still sufficiently awesome. My only real issue is that "Could You Bite the Hand?" sounds out of place; it's good, but the lyrics make it sound like it belongs in Gungrave instead.

I also enjoy Yoko Kanno's music in the Cowboy Bebop series, but I also loved her work on GiTS: SAC!
And Wolf's Rain is pretty good, so I guess I just have to say it's good all around!

For me, it would have be Rahxephon (especially her work with Maaya Sakamoto on "Ongaku.")

Escaflowne, for me, personally.

I would have to say GITS:SAC has probably been my favorite. Particularly, "Inner Universe".
