Stereo field recording. While entering a chamber inside an abandoned lead mine, my foot dislodged a rock and started a slide amongst some spoil beneath me. Recording chain Rode NT4>FEL battery pre amp>Zoom H2 line in.
Thanks for the great sound! Wanted to let you know that we used it in our first game, S.M.A.K. robots. (You can find it on Google Play and the Amazon App Store.) We credited you both in the game and on our website here: http://rockssongaming.com/smakrobots-credits/
