Derek John Lawrence was an Englishrecord producer, famous for his work for Joe Meek's Outlaws, Deep Purple, Flash, Machiavel and Wishbone Ash. Lawrence came in contact with Meek circa at the end of 1963, when he managed a group, Laurie Black and the Men of Mystery, that won a recording session at Joe Meek's studio. He continued working for him until 1965. He brought him Merseybeaters Freddie Starr and the Midnighters. In the late 1960s, he worked for Harold Shampan at Film Music and as freelance producer for The Pretty Things, The Zephyrs, The V.I.P.'s, The Nocturnes etc. He produced Jethro Tull's debut single "Sunshine Day". Ritchie Blackmore, whom he had known from previous work, invited him to work with Blackmore's new band, and as a result Lawrence produced Deep Purple's first three albums, the first at Pye Studios in London and the next two at De Lane Lea Studios, Kingsway, London. He produced Flash's first two albums, Flash and In The Can, both at De Lane Lea. After struggling with Flash's ex-Yes guitarist, Peter Banks, he recommended that the band replace Banks, and suggested several top names. It was advice that they failed to heed, which led to the band's abrupt break up while on tour after the release of their third self-produced album, Out Of Our Hands. He produced Wishbone Ash's first three albums Wishbone Ash, Pilgrimage and Argus, and returned to produce their ninth album No Smoke Without Fire. In 1974, Lawrence partnered with noted session musicianBig Jim Sullivan to form the record label Retreat Records, also the home for Sullivan's Big Jim's Back. Lawrence co-produced Sullivan's new band Tiger, featuring future Samson vocalist Nicky Moore, who released three albums before splitting up. Stateside, Lawrence and Sullivan co-produced the first two albums by the Kiss championed Casablanca Records signing Angel, Angel and Helluva Band, respectively. Lawrence also helmed Legs Diamond's self-titled 1976 debut. At the turn of the decade, he oversaw the MCA debuts by a pair of NWOBHM contenders, Fist's Turn the Hell On and Stand Up and Fight by Quartz, both issued in 1980. Returning to his home country in 1979, Lawrence reduced his involvement, but worked with both Carl Wayne and Hot Chocolate's Tony Wilson in the 1980s. Lawrence died on 13 May 2020, at the age of 78.
