David Anthony Brock (born 20 August 1941) is an English musician and multi-instrumentalist, best known as the founder, the sole constant member and the musical focus of the space rock group Hawkwind.

His father's brother introduced him to music, giving him a banjo at the age of twelve, and a school art teacher encouraged him in his learning.

[3] After leaving school in 1959, he undertook several jobs including work as a capstan setter, before moving to an animation company, Larkin Studios.

He pursued his interests in music at night, although with no initial intentions of it becoming a career, attending clubs such as Eel Pie Island, playing New Orleans trad jazz and blues, and busking with friends such as Eric Clapton, Keith Relf, Jeff Watson and Mick Slattery (born Michael Daniel Slattery, 15 February 1946, Richmond-upon-Thames died 17 March 2023).

[a] With the psychedelic scene burgeoning in London and the band using LSD, their music changed with them starting to use electric instruments and effects units.

[3] In April and May, Brock joined the Buskers tour of the UK, which travelled around the country to each venue in a red London Transport double-decker bus.

A music paper advert brought in teenage drummer Terry Ollis, while friends Nik Turner and Dik Mik were invited to join the band on saxophone and electronics respectively after the pair had originally offered their services as roadcrew.
