Ambient Music
of the 'Brian Eno - On Land' type.
I just stumbled across a friend of a friend's band's myspace page through last.fm (I love that that sentence would have made no sense 4 years ago) called Patel Pretal (http://www.myspace.com/patelpretal) and was fascinated by what I heard. I can' say I 'liked' it, but it intrigued me, and I followed some links around to listen to some more by similar groups.
Anyone care to recommend some particularly good/interesting stuff for someone who's never really investigated this type of music before? That it's 4:30 in the morning may have a lot to do with this sudden burst of interest...
