Toe from Japan

Toe is another great instrumental band. The drummer is pretty ridiculous and makes the beats look so easy and incorporates a lot of different 'sounds' (for lack of a better word). I'm way into this band and of course they're an international band... so there's a fat chance I'll ever see them live.

I've been listening to them a lot. As well as humming their tunes since that's really all you can do for an instrumental band. Their album, City of Echoes, is great. Really low key and chill but does not drone on. It's perfect for when you aren't 'in the mood' for anything that's on your ipod.
