Steel wool burning on a piezo contact mic

Recorded with two DIY piezo contact mics paired with Hosa MIT-129 Impedance Transformers into a Sound Devices MixPre 3 II recorder. The piezo was heavily amplified, resulting in it picking up ambient sounds from the air as well. You can hear the lighter clicking and the “bass” on the end of the video is a car passing by my window. Feel free to sample or use this sound any way you want.
