Acid Test continues their journey with the return of Achterbahn D'Amour. On their first proper release in three years, Jool & Iron Curtis patiently craft an intricate sound world - with the opening track, major-key pads hearken towards a bright future, hi-hats rustle like leaves and on "Dehaveland," percussive elements fall into beautiful, random unison like factory machines staging an after hours dance. Samuel Van Dijk's vaunted VC-118A project steps up for a remix, turning in a taut techno version that unfurls smoke pillars of ghostly ambience. The duo wraps up the four-tracker with an unexpected dreamy electro turn, "Don't Talk To Me." Throughout Acid Test 13, they remain in lockstep with the label's ethos - to bend, hammer and flatten acid lines into new, imaginative shapes.
