According to Discogs...

Tubulence was released April 2002 and Hydraulix 13.2 was August 2003.

However it also notes that the tune on Hydraulix was previously out on xyrys. The only 2 eps that were released on xyrys by the guy who done the track (Guy called Ben aka milanel) were released in 1999 and 2000.

So i'd reckon that one was around first.
