You might have heard of Happa by now. He’s the Leeds native who first burst onto the electronic scene in 2013 with his blistering 12”single “Beat of the Drum/ Bring It Back”, the wildly precocious teenager (also known as Samir Alikhanizadeh) who won instant fans in the likes of Mary Anne Hobbs, Loefah and even Four Tet, the one who scorched a trail with his dark, bass-heavy sledgehammer house, which sounds quite unlike anything else out there right now.

Starting with the urgent, unnerving undertow of “Chewy Teeth”, it becomes abundantly clear that the last three years have seen a qualitative axis shift for Happa; his aptitude at marrying pounding beats with dark, ominous landscapes has been sharpened to a knife edge, his way around a foreboding bass has become laserlike. “Ascension” takes things even further, with surging beats and rattling vocal declamations threatening to send the entire track skittering out of control. Closer “Crickets” with its throbbing, subterranean pulse slowly opens out into a refracted strain of house at its most urgent and unnerving.  “Part 1” is the sound of a young artist refining his sound, with an unerring instinct for the jugular, and many more surprises up his sleeve. You’ll be waiting on tenterhooks for the next installment.
