Heinrich is a bit of an enigma. Having released some 12"s on Detroit's Plus 8 Records (as Sysex), Force Inc. Music Works (as Absolute) and Disko B (as Festival) and his own label Jakpot (both as Festival, as well as Co-Jack, together with Olivier Bondzio aka Hardfloor), he more or less disappeared from the face of the earth. It is said that he is a developer of children's apps for mobile phones nowadays.

The 5 tracks on this 12" are centered mostly around the 909 drum machine and the 303 bassline synthesizer. While two bulky techno tracks feature on side A, the flipside is completely dominated by acid tracks, most of them receiving high praise when they hit the dance floors in the mid 90s.

More recent techno heroes also know how to appreciate these vintage tracks, like Dutchman Danny Wolfers, aka Legowelt, who had this to say about 'Pump Track' on his Facebook page: "Such a fun track, how it stops and starts, almost falls apart. It's mentally challenged simplicity with a giant hall rave vibe... total dance floor control track. On the super cult U-TRAX, one of the coolest Dutch labels from the 90s!"

Original release date: Fall 1994.
