Might as well post this here, I made this back in 2010.
I used this gong sample in the song: http://www.freesound.org/people/timdrussell/sounds/51837/
it was the only sample i used. the rest was made by me for the most part, with a the drum loop being one i got from a free sample pack from some site.
here is the song: http://soundcloud.com/digital-values/trip
