Joshua Abrams is a bass-player, bandleader and composer - often associated with musicians of the free/avantgarde jazz-scene in Chicago. His band Natural Information Society uses an array of traditional instruments from all around the world to create droning, rocking soundscapes that go on for as long as you’d like them to. Here he is on his own with the guimbri - a three stringed skin-covered bass plucked lute used by the Gnawa people
