Belbury Poly is the studio band of Ghost Box Records co-founder Jim Jupp.

Working with analogue electronics and wide range of unusual instrumentation and more recently supported by session players on drums and guitars, Belbury Poly's sound is characterised as a kind of upbeat, electronic and rustic prog rock.

Influences, range from old library music and TV soundtracks to keyboard driven 1970s prog rock, folk and Krautock.

[1][2][3] Jupp has spoken about Belbury Poly and the other artists on Ghost Box as sounding like the misremembered past of a parallel world,[4][5][6][2] as well as acknowledging a debt to the author Arthur Machen.

He is also a member of The Belbury Circle along with Cate Brooks (of The Advisory Circle) and occasional collaborator, John Foxx[8] In 2019 he co-wrote and produced the music and spoken word album Chanctonbury Rings with Justin Hopper and Sharron Kraus.
