Since last week's puzzle has not been solved yet, I have decided to extend the MP3-identifying contest series with one more mystery MP3. This is again the first part of a longer track, and it has actually been played on WFMU, at least twice. The first one to name artist and/or album in the comments will get a prize in the mail.
As an added bonus, this album has something in common with last week's, so maybe you can still guess that one. Good luck!
