For his debut on Spectral Sound, San Francisco DJ/producer Matrixxman presents Amulet -- rich with analog ideas, and exploring his interests in deep Chicago moods juxtaposed with techno futurism. Using a number of classic Roland pieces, Duff fluctuates between bouncing house rhythms and hypnotic techno. Most notably of the latter style is "The Caravan," with hefty, driving syncopation under scrubbing, distorted hints of melody. "Venetian Mask" goes deeper with a hint of restrained jacking, setting up for "Enter Me," an infectious Balearic excursion. "Scimitar" leans closer to a UK style of dubbed-out bass, coupled with an estranged yet futuristic touch of deep house.
