Many years ago, I used Adventure Game Studio to design and develop a point-and-click adventure game called The Bunker. It wasn't especially good, but if you're interested for some reason, it is once again available on Mediafire: Here. I can't guarantee that it will run on your computer, but I'm not sure of any particular reason why it wouldn't.
Anyway, one thing that I really liked about the game was... well... some of the music. But the game only made use of MIDI for that, and so its quality depended upon the soundcard in the player's computer, and thus it wasn't always particularly fantastic.
Well, to make a short story even shorter, I created a remix of one of my favorite numbers from The Bunker, namely the theme that plays when you meet the crew of the Sand Sub. That is, a submarine-like vehicle that travels under the sand. The remix can be heard at my Soundcloud profile, along with a few other tracks that I've written.
There is a guitar solo in it that isn't particularly great. I recorded it in like half an hour and with only a handful of full takes. If this were a more serious endeavor, I'd have spent far more time with it, but meh...
