the demo tape has some tape hiss and the last two tracks have quite a bit of hiss, so a little cleaning will help. But, there are a few other sounds that i find very interesting that you would not usually hear on a professionally produced recording, and those sounds are little chair or bench squeeks. Probably from Vanessa while she adjusted prior to starting the song. It makes the tape very real. kinda cool. One squeek is at the beginning of Meggie Sue, one of my favorite new songs from the "demo tape". just fyi. I like those little flaws. very artistic.
