1970s and experimental poetry
During the 1970s, with Second Aeon magazine at its height, Finch became deeply involved with experimental, concrete, sound and visual poetry. He had met Bob Cobbing in London and had been drawn to the innovative often anarchic styles practised in the capital. Finch became treasurer of the Association of Little Presses (ALP), the Welsh representative of Poet's Conference, the poets trade union, and a council member of the Poetry Society in Earl's Court.
In Wales, he had been elected a member of the English Section of Yr Academi Gymreig, the Welsh Academy, the august association of writers, and was regarded by some as its an enfant terrible.
His work, often in the form of extended sound poetry innovations, was performed at venues throughout the UK. His visual poetry was exhibited in the company of Peter Mayer, dsh, Cobbing and others, both in the UK and further afield. He was awarded a Welsh Arts Council bursary for visual poetry. The University of California exhibited both his concrete poetry and Second Aeon magazine artefacts.
Richard Kostelanetz called him "the principal innovator in Welsh poetry... Finch has favored a variety of tight sober structures, including parodies of other poets, visual poems, sound poems, and verbal imitations of Philip Glass' music... Finch deserves a Welsh knighthood".
