I've been aware of this album for as long as I can remember - it was only when I got into the whole music2work2 thing that I really started to listen to it.
Put back on my radar by David Dobbs as part of Steve Silberman's epic post on authors and their favorite "writing" music - I did crack up over his comment on the danger of using such chilled out ambient music:
This makes the playlist because it's such a great example of classic ambient background music, but I tend to agree with David in that it's almost too low energy. A good one if you're already in the zone and just need a little aural maintenance!
