I just thought I'd share this beautiful track and equally stunning video with you.  This is Mike Oldfield's second production in the "tubular bells" series, the first of which was recorded in autumn 1972, one of the earlier synthesized electronic tracks to reach a mass audience in the movie, The Exorcist.   Sentinel is a revisited version, much better in my opinion, and was released in 1992.  I was lucky enough to find this on 12" in Ithaca at a record fair last semester.  Anyways I think the music and the video are both really interesting and you might want to take a few minutes from your hectic day to lose yourself to this.
