The gritty dark swamp blues sound of Dusk Brothers (Gray and 'E' Moncrieff) draws heavily on their unconventional arsenal of self-built instruments. Guitars fashioned from old metal boxes, "Frankenstein" foot drums created by ripping down 55 gallon oil drums and bolting them onto sawn-off bass drum shells and custom valve guitar amplifiers built from scratch in their own workshop provide a raw, bluesy backdrop for growling vocal harmonies and blues harp.
