"Groove is in the Hertz" includes a selection of recordings, showcasing the perspective of GummiHz on minimal house and techno. The series is split into parts with part one featuring two minimal cuts. "Aerini", on side A, offers eleven and a half minutes of minimal techno bliss. Anthemic voices combined with live recordings set a balearic atmosphere, while sitting elegantly on top of finely programmed rhythmics and bass lines. Flip it over and "Out Out" brings out even more rhythm to the game.
