are an Anglo-Dutch experimental rock band formed in London in August 1980. In 1984, the band moved to Amsterdam, playing with rotating musicians and having, as core members, singer/songwriter/keyboardist Edward Ka-Spel and keyboardist Phil Knight. In 2022, founding member and synthesist Philip Knight retired from touring, and Randall Frazier (Orbit Service, A Star Too Far) joined the band on synths, samples and electronics.

As of 2022, the group is composed of Edward Ka-Spel (vocals, keyboards, songwriter), Randall Frazier (keyboards, electronics), Erik Drost (guitars) and Joep Hendrikx (live sound engineer).

Their music has incorporated elements from neo-psychedelia, ambient music, electronic music, tape music, psychedelic folk, synthpop, post-punk, progressive jazz, noise music, pop music, goth rock and alternative rock. Although outside the mainstream (in terms of their avant-garde music and non-mainstream career path), LPD have released more than forty albums, have a devoted worldwide following, and tour frequently.
