In the first of the NJW’s free concert series, the duo Concurrence brings their experimental improvisation to the Cave. Concurrence consists of pianist/keyboardist Paul Horton (Brittany Howard, Alabama Shakes) and bassist/broadcaster Greg Bryant, who come together to create a highly improvisational music duo but also a research collective. The band’s newest project, Indivisible, focuses on an overlooked era of American history, the creation of the Interstate system, which with all its successes also irrevocably altered Black and Brown communities across the country.
