Throughout the high frequencies (sorry/not sorry) and classic rock jokes, it's undeniable: Piper Curtis is a serious musician. For one, taking electro-acoustics in university is badass af, and two, Piper is serious about experimentation, and knows how to do it really well. . Track 1 is a study in Hz: Piper generated sine waves of 60 Hz, 600 Hz and 6000 Hz. I generated sine waves of 40 Hz, 400 Hz and 4000 Hz. We then played with the levels of each wave, and later on in the track, I add a 4 Hz wave that soundn't be audible (to humans at least) but as I increase its level the undertones of the two waves interacting come out in a "wHopwHopwHopwHop". Track 2 is us playing with samplerates, specifically 8 Khz. We attempt to sing at that frequency, and in a way, glitch the recording. "A fun and exciting trip to the mountains ends abruptly" is set to the percussion of Piper and I trying pretty hard to break a nalgene water bottle. It didn't break. By the end of the album we were getting pretty nostalgic and bratty, so we went way back and ran vocals through her childhood fisher-price tape recorder, doing kareoke over things that sounded like springsteen. Then this one banging track that sounded nothing like springsteen came on, and we danced. more info on subharmonics featuring the experimental genius of piper curtis January 2018
