Beastie Boys- Hello Nasty i just discovered the trip potential of this CD a month or so ago.. this may seem like an strange choice but its by far my favorite to listen to on any drug, although i generally only listen to the (absolutely fucking BRILLIANT) instrumentals.. if you dont have it, id recommend downloading tracks 4, 14, 15, 18, and 22 and putting them on a loop in winamp next time you decide to trip.. YOU WONT BE DISSAPOINTED..
