I was trying to describe the lyrics of a song today and stumbled when I reached a section with a bunch of "la la la" bits. I suppose I could have well just termed them as la-la-la bits, but seeing as to how I apparently have all the time in the world (not my words), I decided to see if there was something a bit more definitive that I could use. A wittle googling later, I chanced upon the answer.
So, thanks to a lot of hype, I ... acquired this anime and watched it all in a couple of sittings. I'm a real sucker for anything that revolves around music and the fact that this is directed by Watanabe Shinichirō (director of Cowboy Bebop, Samurai Champloo, etc., who is known for blending music in really well) with music taken care of by Kanno Yōko (who is a bloody legend), is about as big a recommendation as any anime can get.
It starts off with a jazzy drum intro which subsequently builds up into this high speed rhythm into which is merged Beck's intense driving verse riff... a series of pressure-building scales that are just about to take you off into space. The second repeat also sees the keyboards being introduced, playing the same scales.
