Biography
Showing the Discogs bio
Denis Blackham has been mastering music since joining I.B.C. Studios in 1969. For 27 years he cut vinyl, signing the dead wax as BilBo. Some 7" (45) releases have 'A Bilbo Boppa', 'A Bilbo Egyptian Boppa!', 'A Bilbo Rollercoaster!' or even more etchings. After leaving I.B.C. in 1973, Denis worked for various companies including Phonodisc Ltd., RCA Studios, London, The Master Room (1976-77), Nimbus Records (1977-78), Tape One (1978-89) and Porky's Mastering.
Since 1989, he has concentrated on CD mastering. In 1996 Denis started his own Country Masters facility at his Surrey home. In 2002 he moved to the Isle of Skye and changed his company name to Skye Mastering.
