Underground Quality's latest twelve inch endeavour sees husband and wife team Jus Ed and Jenifa Mayanja introduce the first in a series of collaborative EPs under the EDJ prefix. This murky purple twelve sees Ed act the gent and allow the A Side duties to fall on Jenifa's shoulders, and Mayanja responds with a delightfully idiosyncratic house jam in "Dark Matter". The track's early moments present a dusty, percussion heavy tribal groove that slowly builds into a glistening procession of future thinking house dynamism. An unannounced swerve into a rippling acid bassline mid way through proves inspirational. In contrast to the laid back nature of this track, Jus Ed opts for a much rowdier approach with "Slammer", all ebullient house stabs and constantly rising string flourishes over the rasping four four kicks.
