Gavin Sutherland aka Fudge Fingas is the man behind the seventh missive for the peerless Firecracker imprint, with "What Works" showing a move away from the soulful strains of his recent long player for Prime Numbers and towards moody, shuffling Detroit house. It seems fitting that remix duties are handed to Vakula - it was Firecracker after all who first showcased the Ukrainian producer's sounds to a wider audience - and despite his prolific form in recent times, his appearance here still feels very special indeed. Unsurprisingly, he turns in a memorable, highly atmospheric remix of "What Works", before another Fudge original, the chiming sea of calm that is "Mass X", rounds off an essential release.
