Gary Marx (born Mark Frederick Pearman) (born 18 June 1959) is a founding member of British rock band The Sisters of Mercy and its lead-guitarist and songwriter from 1980 to 1985.
He left the band in 1985 to form Ghost Dance, which included ex-Skeletal Family vocalist Anne-Marie Hurst. They released two albums and embarked on a number of extensive tours enjoying relative success. However, record-company politics and inconsistency in personnel left the outfit reeling and they had disbanded by the end of 1989.
From 1997 to 2005, he worked as a teacher at Paul McCartney's Liverpool Institute for Performing Arts. He subsequently released material as an independent artist through his own website and set up an archive for his previous band, Ghost Dance.
In 2003, Marx released his first solo album, Pretty Black Dots.
In 2007, he released the Nineteen Ninety Five and Nowhere album, with material originally written by him in 1995 for The Sisters of Mercy, at the invitation of Andrew Eldritch.
