Paul Douglas mentions, "Scratch had a particular sound and everybody was fascinated by his sound. He had this way of putting things together; it was just his sound and it influenced a lot of people. I’ve even gone to the Black Ark with Eric Gale for that Negril album; I remember myself and Val Douglas, we laid some tracks there, Eric Gale overdubbed stuff on there, but I honestly don’t remember what happened to it." Lee Perry and his studio were also formative in creating the highly innovative reggae subgenre called dub, in which the producer/engineer becomes the focus of the music, manipulating a pre-recorded track and creating something entirely new using the mixing console as nothing less than an instrument. Perry worked with The Clash and Paul McCartney and his band Wings had recorded there between 1972 and 1979. In 1979, following years of increasingly bizarre and erratic behavior, Lee "Scratch" Perry, armed with a magic marker, covered every available surface of the Black Ark with impenetrable writings before allegedly burning it to the ground. This event, with the loss of the studio's unique sound and a hiatus in Perry's extraordinary creative skills, effectively ended an era during which much of Jamaica's most innovative sounds had captured the world of music. However, it has been related by several Perry family members that the studio in fact caught fire in 1983 after an ill-fated attempt to rebuild it, the result of an electrical accident. More often than not, Perry has claimed that he personally destroyed the Black Ark due to "unclean spirits" - an allusion to some of the undesirable people who were constantly at the Black Ark in later years. There are also stories that Perry was being blackmailed by gangsters who wanted a cut of the record profits. Perry himself stated in an interview with clashmusic.com regarding the fire, "Too much stress in Jamaica, all the time. Everybody want money, everybody want paid. Everyone got problem and want me to solve their problem. Nobody gave me anything, people just took everything. Everybody take this, and take that. So the atmosphere in the Black Ark studio was changing; it wasn’t like it used to be. Then I decided to make a sacrifice as the energy wasn’t good anymore." Shortly thereafter, he moved to London and then Switzerland.
