There’s drumming heritage in Sonny’s family, as his dad is Hughie Flint (John Mayall’s Bluesbreakers, the Blues Band, McGuiness Flint). So unsurprisingly the first time Sonny played the drums they were his Dad’s.

When Sonny was 13, his Dad gave him an old Ajax drum kit as a present and Sonny has been drumming ever since. Sonny is a self-taught drummer and he learned to drum by listening and playing along to Led Zeppelin and Beatles records at home after school.

Sonny’s first band at school incorporated influences from prog and glam rock bands into their music. He then went on to join the psychedelic band The Limbic System from Barnet before being headhunted by anarcho-punksters Omega Tribe in 1984 to go on a UK tour at the age of 17.

​Since then Sonny has played and recorded with 13 Frightened Girls, signed to Stephen Street’s record label, the Silverjets, signed to Blanco Y Negro, who toured with Catatonia, played with Russell Senior (Pulp), played and recorded with Me Against Them, who were John Peel favourites, Heidi Jo Hines, Simon Eugene, Emma Wilson’s Monarch Blues Band, and Pete Fender. He worked with David Knopfler (ex Dire Straits) on the song ‘On The Line’, which appeared on the album 'Shooting for the Moon', released in 2021.

​He’s also a professional sound engineer and has toured with Das Pop, Is Tropical and the Blockheads as their chosen sound engineer, has recorded Seasick Steve, Gary Numan, Emiliana Torrini, and Dhani Harrison, and has had the pleasure to work at the 100 Club as their house engineer when Paul McCartney, Chuck Berry, and James Burton played.

​When the 2020 Lock-down put an end to live performances, Sonny used his sound engineering knowledge to kit out a professional home recording studio and invested in a number of high-end Ludwig and British Drum Company drum kits and snare drums, as well as vintage Ajax and Premier drums and vintage Ludwig snare drums, which has allowed him to do remote drum recording and song mixing.

In June 2022, he joined Martin Turner, ex-Wishbone Ash, completing five tours throughout the UK, Germany, Belgium and Holland.  In July 2024 Martin Turner ex-Wishbone Ash with Sonny on drums joined Asia, Focus and Curved Air on Asia's ‘Heat of the Moment’ tour, which took the band to 19 venues across the East coast of America.

Sonny left Martin Turner’s band in November 2024, and then joined forces with critically acclaimed singer / songwriter Claire Hamill. They immediately started to work on new material, which is recorded and mixed in Sonny’s studio.

In January 2025 they were joined by three other fine musicians and are now performing as the Claire Hamill Band, with their first single released in March 2025 and a full album planned for later in 2025.  Sonny also continues to record drums remotely for other artists.
