Underground house music is alive and well in Poland. Need proof? Direct your attention in the direction of Twins of Sound. The Olsztyn-based duo formed in 2007 and have held DJ residencies at clubs in Warsaw, Sopot and their home town. Since their union they’ve been carefully forging their own take on all things 4/4 and have made wonderful progress. We’ve got the world premiere of the twosome’s new floor mover, “I Wanna See You Jack,” set for release on April 29 via their TOS label. The pumping house jam undoubtedly draws influence from a wealth of Chicago producers, yet the pair are careful to embed their own brand of funk into the track’s grooves. Jack would definitely approve.
