An interesting thread came up on the Analog Heaven list regarding the first tracks to feature the TB-303. The following are a handful of them in order of release. Note how the TB-303 is more used in it's original intent as a substitute for bass guitar - no acid here. As Blancmange was the first on this list, I thought I'd put up a picture of them with the 303. I found the image on The Daily Disco. If you know of anything earlier with the TB-303, feel free to comment.
