Internal Sync are Jackspot and Calapez. The Portuguese duo made fame within a short period of time. Their debut EP Zero Zero for German label Klang Gymnastik was released in March 2007 and sold out within no time. The Ampere remix taken from this single was comped by D. Ramirez & Mark Dynamix on the Ministry of Sounds Discotek compilation. On Fortek we bring you their deep techno cut Dif Dif. A rough bassline supplies for the bounce and the minimal drum programming hits the spot. The duo go crazy with a housey juno-esque synth. With some tweaks and effects this track is a floor banger for sure. On the b-side we have Fortek wonder child Mr. Tretau on remix duties. He takes Dif Dif into even deeper territories adding a tech-club feel a la Ame and Charles Webster. The mix slowly builds and builds. A wonderful voyage. Killer package!
