These investigations were performed prior to the founding of 417PRG. They were done so with and under a different group name. Since then founding of 417PRG, that group unfortunately no longer exists. All credit for these investigation goes to that group. Since half of 417PRG were present during the time of these investigations, we have listed them as experience only.
YOU MAY HAVE TO TURN UP THE VOLUME OR USE HEADPHONE ON SOME OF THESE. HOPE YOU ENJOY!
