Hopper is best known for his work as bass guitarist for the band Stump,[1] an Anglo/Irish indie/experimental/rock group formed in London in 1983. Stump released two albums, the self released mini album Quirk Out in 1986 and their only full-length release A Fierce Pancake in 1988.[2] Since the late 1980s, his mainly instrumental output has been diverse and best described as a hybrid style of experimental and melodic pop with his distinctive bass playing often to the fore. He has also created electronica with the group Ticklish[3] and minimal pulse music in a Rock band format with Prescott[4] (formed in 2012) featuring Scritti Politti keyboardist Rhodri Marsden, drummer Frank Byng, adding Pere Ubu guitarist, Keith Moliné in 2016.
