In 1986 Ray Hayden opened Opaz Recording Studios in Hackney, by 1992 Opaz had become one of the leading recording studios for black music in London and he started Opaz Productions. Its first record, Martine Girault's Revival, went straight to Number 1 in the Dance Chart and Ray went on to become an internationally renowned producer and singer and Opaz an established independent record label. His credits also include Mica Paris, Marvin Gaye, Will Smith, Mary J Blige and his work has featured in major Hollywood films, TV shows and advertising. Ray used his position and resources to co-found The British RnB Association which brought about the first official Black Music Chart in the UK. The RnB Chart was essential as a reference for the American market for the successes of artists and musicians hoping to export their work to that territory. It was published weekly in Music Week magazine and the Top 30 was counted down every Sunday on Kiss FM, hosted by Trevor Nelson.
By 2002 he gave regular Master Classes in Production and Mixing at Guildford Music Academy, hosted seminars for the Musicians' Union and was approached to set up a college with a local charity based in Hackney Wick called UXL.
