I downloade paulstretch for OSX a while back, around the time of the ZOMG Justin Beiber @ 1/8 speed = Sigur Ros phenomenon. I used it on a few gabba tracks to odd and amusing effect. One of these days I might get around to post some expamples. Don't hold your breath on that one.

Baked Beans were a trio of German ambient composers. They put out two albums on the short lived Recycle of Die label in the mid 90s, and one more a different label toward the end of the decade. Physical copies of their CDs are stupidly hard to find, but in the age of FLAC most of their catalog is attainable. This song was my first exposure to their music. It was included on the Eye-Q compilation pictured in the video, which actually had some distribution in the US. As it turns out, the song is one of Baked Beans' strongest works, and is dedicated to Heinz Roth, the founder of Recyle or Die.
Like many (most) ambient works, it's a bit slow to start. When it finally gets to where it's headed, this song displays some pretty fantastic analogue synthesis. Well worth 11 1/2 minutes of one's time, provided the listener is in a quiet, relaxed atmosphere. Then again, I dunno, this track might work with closed to cans to block out a noisy and hectic workplace.
