Damian began recording music in 1991 with the band Landmarq and featured on their first 3 albums. In 1993 he recorded his first album with Threshold, ‘Wounded Land’. He would return for 3 more albums.
In 1997, Damian's debut solo album 'Cosmas' was released. This album was a departure from the heavy/progressive rock sound that people had been used to. He managed to surprise people even more by landing the role of Jean Valjean in Cameron Mackintosh's touring production of Les Misérables. He played lead role for two years.
In 2000 Damian fronted Rick Wakeman’s Rock Ensemble and toured and recorded with them for two years. During that time he also featured on several Ayreon albums. This collaboration with Arjen Lucassen would result in three more Star One albums.
He formed the progressive rock band Headspace with Adam Wakeman in 2007. They released an EP and began writing their debut album ‘I Am Anonymous’. As part of a 3 album deal with InsideOut Music, the second Headspace album was released in February 2016.
Damian’s 5th solo album ‘Built for Fighting’ was released in September.
