Nick Knopf is a computer programmer by day with a hobby as a highly unique psytrance DJ named Ziptnf (that's Zip-Tee-N-F) by night. He is committed to providing top quality mixes in a variety of styles with his signature psychedelic sound. His sound can cater to many tastes, from folks who dig relaxing chillout to those underground ravers who live for heavy, sinister basslines.
