The Koch Marshall Trio formed because of the persistence of drummer Dylan Koch. The band members were all schooled in jazz and blues: the jazz background allows each member to be comfortable with the improvisation which is evident in their live performance.
Greg Koch said the band came together when his son Dylan Koch convinced him to meet Toby Lee Marshall one afternoon. The three musicians got together to play at a local recording studio. The three players all felt like they had a connection. The Koch Marshall Trio is an instrumental group: Greg Koch established the organ/guitar/drums trio in 2017 which includes Greg Koch's son Dylan Koch on drums, Toby Lee Marshall on the
B3 organ, and of course Greg Koch on the guitar. The Koch Marshall Trio has signed a contract with the
Mascot Label Group. They released their debut studio album on February 23, 2018 (
Toby Arrives) under Mascot's 'The Players Club' label. ==Style and legacy==
