Mad Professor (born Neil Joseph Stephen Fraser, 1955, Georgetown, Guyana) is a Guyanese dub music producer and engineer known for his original productions and remix work. He is considered one of the leading producers of dub music’s second generation and was instrumental in transitioning dub into the digital age. He has collaborated with reggae artists such as Lee “Scratch” Perry, Sly and Robbie, Pato Banton, Jah Shaka and Horace Andy, as well as artists outside the realm of traditional reggae and dub, such as Sade, Massive Attack, The Orb, and Brazilian DJ Marcelinho da lua.
Fraser became known as Mad Professor as a boy due to his fascination with electronics. He emigrated from Guyana to London at the age of 13 and later began his music career as a service technician. He gradually collected recording and mixing equipment and in 1979 opened his own four-track recording studio, Ariwa Sounds, in the living room of his home in Thornton Heath. He began recording lovers rock bands and vocalists for his own label (including the debut recording by Deborahe Glasgow) and recorded his first album after moving the studio to a new location in Peckham in 1982, equipped with an eight-track setup, later expanding to sixteen.
