Grin house (also known as GrindHouse, Grindhouse, Gryndhouse, Mühlehaus) is a type of electronic house music that conforms to a set of rules known as The Ten Commandments of Grind House. The style is characterized by the absence of harmonic progression, a kick drum placed on both the downbeat and backbeat of every measure, the application of reverberation on the kick drum, heavily processed percussion, the absence of non-musical phrases or samples, and monotonic bass lines which also serve as the music's only melodic content. The style was developed in rural Oregon by electronic musician Chris Randall.
