In the 1960s and 1970s he edited the ground-breaking literary magazine, Second Aeon, exhibited visual poetry internationally and toured with sound poet Bob Cobbing. In the 1980s and 1990s he concerned himself with performance poetry, was a founder member of Cardiff's Cabaret 246 and of the trio Horse's Mouth. This was work with props, owing as much to theatre as it did to literature. In the new Millennium he was worked on psychogeographies and alternative guides to his native city of Cardiff. The city has become his obsession.

Finch lectures throughout the UK, often on the subject of Cardiff and urban living. In addition to the readings Finch also delivers a number of presentations on the poetry publishing scene (how to get yourself published - a demystification of the arcane world of books, magazines and the internet), on the history of sound poetry (which features histrionic performances of dada texts and the playing of numerous historical recordings), on the writing of short fiction and on the history of the small press. He works with schools and has led young people's writing squads in co-operation with local authorities.

From the early seventies until the late nineties he was treasurer of ALP, the Association of Little Presses. Between 1975 and 1998 he ran the Arts Council of Wales's specialist Oriel Bookshop in Cardiff. In 1998 he took up his current post as Chief Executive of Yr Academi Gymreig/ The Welsh Academy - the Welsh National Literature Promotion Agency and Society for Writers.

Peter lives in Cardiff and has three children, Belinda, Daniel and William, from his first marriage.
