Of course!! Both tracks have as their base a time-stretched sample from a synthesizer – I think an MS-20 mini – that was originally around a few seconds. “December” is filled out with some triangle wave, as well as some resonating filters from the MS-20.
The percussion in “January” is actually an electric guitar, time-stretched out of whack and pitched down. Some extra help with mastering that one came from my friend Andrew Lee, of Holy Hum, whose stuff is very worth checking out, too. Especially “Appendix C,” which played a big part in giving me the courage to compose longer songs.
