Having fun with binaural recording. With microphone spacing the same distance as your ears, wearing headphones to listen to these makes for somewhat realistic audio.
Random Jam - walking through a hallway of rehearsal rooms making for a very random song.
Outdoor Gathering - Approaching and walking through a spontaneous party.
The Drill - Having a cavity in my #15 molar drilled out. Bone crunchy goodness!
Street Preacher - A belligerent crowd debates a street preacher. (not binaural, but I'm throwing it in, anyway)
