I made this when I first got started in music production. Maybe 2003?ish....
I used Acid 2.0 for the beat loop and to make the arrangement.
I recorded this by hanging the microphone between my headphones and my ear. This way I could use the one headphone as a monitor, while the other side was off my ear so I could use the loops as a metronome.
I record, and then hit play on the computer, boom. Shitty sound quality, but whatever.
