Kev Hopper is probably best known for his work as the bass guitarist in the band, Stump, an Anglo/Irish indie/experimental/rock group which he co-founded in London in 1983 with Chris Salmon, Rob McKahey and Mick Lynch. Stump released two albums, the self released mini album, Quirk Out in 1986 and their only full-length release, A Fierce Pancake in 1988. 

Since the late 1980s, his mainly instrumental output has been diverse and best described as a hybrid style of experimental electronica and melodic pop with his distinctive bass playing often to the fore. He has released 15 solo albums since 1989.

Two bands dominated his post-Stump years: the electronica laptop quartet, Ticklish (1998–2005) consisting of Phil Durrant, Richard Sanderson and Rob Flint and the funky, bass guitar, angular riff-dominated Prescott (2012–2018) featuring Scritti Politti keyboardist Rhodri Marsden, Not this Heat drummer Frank Byng, and Pere Ubu guitarist, Keith Moliné.

He has played and collaborated with many other musicians such Charles Hayward, The High Llamas, Stereolab, Pere Ubu, Kelsey Michael and free-improvisors such as Derek Bailey…and even played musical saw on the Des and Mel show.
