Released in 2002 as the Drexciya project was forced towards an untimely finish with the passing of James Stinson, Grava 4 remains a high-point in the legendary Detroit electro pioneers' catalogue. As ever, the magic of the record lies in the balance between experimental, provocative sound design and fully physical, instinctive machine funk. Stinson and Gerald Donald were able to say a great deal within the parameters of their project, and Grava 4 remains leagues ahead of what most people think electro can be. Just marvel at the likes of 'Gravity Waves', which feels like the truest representation of the genre without ever following a pre-existing formula.
