British musicians Adam Martin and Mark Slater are the co-founders of Nightports, a collaborative project which explores the freedoms of restriction. Like Matthew Herbert, the duo create music according to self-imposed guidelines. Namely, they state that they only use sounds produced by the featured musicians. However, these sounds can be manipulated and reshaped in virtually any manner. The results range from glitchy experimental pop (2015's Depart, with Emily Lynn) to complex electro-acoustic soundscapes (releases with Matthew Bourne, Betamax, and Tom Herbert), depending on the featured collaborator.
