As a live performer, the one-man band switches between acoustic and electric guitar backed by a kick drum and foot-tambourine. With Tim's distinct, soulful voice layered over compelling instrumentation there is a strong presence of folk, rock, blues and reggae. His third album, Castles in the Trees, was released in early 2018. The album was closely followed by the single 'Wicker'. In March 2020 The Fourth Son released his second single 'Home Again' and relocated to Philadelphia.
