Ten years ago, Acid Test began with a simple concept—each track the label released would make use of the Roland TB-303. Like a producer purposefully paring down their studio setup, or the continuous imperative within underground electronic music to reduce, this concept engendered creativity with the introduction of what seemed to be an aesthetic limit. However, the decade that followed, which now culminates in the triple-LP compilation Ten Years Of Acid Test, proves acid is limitless. That the Berlin-via-LA label would expand upon the classical conception of acid house and techno is no surprise considering the cast of characters that have come in fold over the past decade. Ten Years Of Acid Test gathers key material from the label’s extended family of acid acolytes. There’s that Vienna-via-LA maestro of sad, elegant acid Tin Man (Johannes Auvinen), whose “Afters Acid” is both a highlight within his prolific catalogue and a distillation of his symphonic approach to the 303. Detroit giants Erika and Marcellus Pittman, both of whom have released remixes on Acid Test, present their respective and singular Bass Line visions. Erika, the Interdimensional Transmissions lynchpin, crafts a dark, delicate take on broken techno on “Violet Fungus” while Pittman continues his cubist house explorations on “Unknown Species,” both tracks straying from typical acid lines in favor of the intricate textures achievable on the 303. This variation in approach applies to tempo as well. Irish-based master Lerosa, as well as Delsin affiliate VC-118A.
