Ian Mosley

In 2019 Mosley published his collected memoirs under the title Do I Owe You Money? - The Collected Memoirs Of Ian Mosley

In 2001, Mosley joined saxophonist Ben Castle, son of entertainer Roy Castle, and they recorded a jazz-themed album together, Postmankind. The album also featured guest performances by John Etheridge, Steve Hackett and Marillion members Steve Rothery and Pete Trewavas.

Mosley has acknowledged that until and including Marillion's 1991 album Holidays in Eden, his drumming sound was "very eighties" and featured a "big reverb", but he prefers to record drums naturally and he credits Dave Meegan, who produced 1994's Brave and several subsequent albums, with changing the sound of his drums to the more natural sound which has prevailed since.

Mosley joined Marillion in 1984 after a long search for a replacement for drummer and founding member Mick Pointer, who had left the band acrimoniously in 1983. He was the fifth drummer to play for Marillion and was frontman Fish's choice for the role, who had been unhappy with the band's previous drummers. Music critic John Franck stated Mosley's "spot-on drumming was the perfect foil for Marillion's meticulous musicianship". He is still a member of Marillion.

Mosley studied percussion at the Guildhall School of Music and Drama under teacher Gilbert Webster and, aged 18, played in the orchestra for the musical Hair. His first professional band was Darryl Way's Wolf. Mosley played drums for former Genesis guitarist Steve Hackett, both on two of his solo studio albums and on tour. He played for Gordon Giltrap. He also played on the 1975 album Birds by Dutch band Trace.

Ian F. Mosley (born 16 June 1953, Paddington, London, England) is an English drummer. He is best known for his long-time membership of the neo-progressive rock band Marillion, which he joined for their second album, Fugazi, released in 1984. He had previously been an in-demand session drummer. Mosley's abilities have been widely praised, including by former Genesis guitarist Steve Hackett, Meshuggah drummer Tomas Haake and critic John Franck of AllMusic. Modern Drummer has characterised him as a "drumming great".
