Marathon was formed in 2019 by Mark Kelly, the keyboard player with Marillion. Together with Guy Vickers, Oliver M. Smith (vocalist), Pete "Woody" Wood (guitar,) John Cordy (guitar), Henry Rogers (drums) and his nephew Conal Kelly (bass), Mark Kelly turned his vision into reality. Marillion bandmate Steve Rothery also joined the band and contributed the lead guitar to the song "Puppets". The band recorded their debut album in separate locations between March and July 2020 during lockdown. The members of the band came together (some meeting forthe first time) at Peter Gabriel's Real World Studios on the 28th & 29th of July to record and film a live version of the album, which will be available as a Bonus DVD together with the album.
