A psychologist of rhythm no less, born in Harrow, North London, in May 1963; Harrison's early influences stem from his father's jazz collection. Besides playing on records by Kevin Ayers, Lisa Stansfield, and Iggy Pop, Harrison produced two books, Rhythmic Illusions and Rhythmic Perspectives, and replaced Chris Maitland in Porcupine Tree. ~ Kelvin Hayes, Rovi
