A metallic pad with lfo weaving in and out in amplitude/filter. Includes some lfo modulation, so some peaks are longer than troughs and vise versa. Used in an experimental scene to symbolize birth. Recorded with a roland groovebox self-sample utility straight to wav, which is pretty good sounding. Though i've found this method results in reduced high frequencies.
Just one of a bunch of shoe hits on a metal trash can. I used a home-built contact mic made from a cheapo piezo. This was fed into an h4n and edited in pro tools.
