I'm so glad that you've managed to fathom the Physical Motion - Mystery track - I've been after this little gem since the days of the Sound Factory (1997-98). Do you have any of the old mixes of Steve's that feature this track on it? I could only find the mix from the Monastery in 98 but he did another tape which featured the TDV's the Dawn, Mario+ More - All I Need, Dominator 98, Bassline - Acid is Back etc... - If you have a copy of this tape I would be sooooo chuffed?!
