In case anyone else wants to hear the rough cut, it's here.
ETA: OK, I just realized this person has a bunch of demos, as it turns out, along with some of Matt's REALLY old stuff (does it include the, like, four really old songs I don't have? Does it? IT DOES.) Yay! Now I just wish I could find these in a form I could get on my iPod.
ETA 2: Ooh, a good-quality version of If I Was A Tidal Wave. I love this person, whoever they may be.
