Both are multi-instrumentalists who specialize in playing bass (both upright and bass guitar), the anchoring element on which most dub music is judged. But it's the use of classical instruments that make the standout cuts soar on their album together. "Other Planes of Dub" places a lilting violin played by Daniel Bernard Roumain at the center of the action, manipulating it into the standard dub tools of echo and reverb, and putting it into a context in which it is rarely heard. "Gamma Burst" similarly works with Niels Van Hoorn's live saxophone and flute amid twinkling keys, recalling stars and space dust. What's refreshing about Riddim Clash is that while it's fundamentally influenced by sounds from the island, the two artists thoughtfully mine new territory, rather than rehash Jamaican stereotypes.
