Purple Caps' crunchy, totemic title track is typical of the EP that wrestles the baton from Urals: static is rolled into a grotty ball and tossed through a gauntlet of junkyard percussion and cheap plastic. But Willis treats these ugly sounds with care. There's an Ostgut Ton-esque sleekness to "Azimuth," but its gently crumpled edges are in keeping with Purple Caps' scruffy charm. Then there's "Q-Type," whose acid-scarred bass synths and doomy atmosphere are daubed with unexpectedly fun flourishes. (After the three-minute mark, a shriek signals a doubling-down on the frenzied percussion.)
After "Tides Of Lust," a muscular preface to "Q-Type" that first appeared alongside "Purple Caps" on a split-EP for Obsession Recordings, comes a remix by the other half of Walls. Under his Not Waving alias, Alessio Natalizia pulls the tangled synth lead through a suite of 909 percussion. The trick gives his remix legs as a DJ tool, even if it feels like a few too many ideas were thrown into the mix.
