A side brings a crazy tune, a tune that you can stand as a 180 BPM tune as well as a 137 BPM tune... and this is when played 45 RPM.. you can play this one 33 RPM too.. for another big change... an ideal weapon for a Deejay who want to change speeds during a mix... crazy stuff !!! B side brings 2 tunes : one Industrial techno bomb and one acid screwdriver, a very friendly B2:) ENJOY !
