Following a second album, What We Did on Our Holidays, the group's male vocalist Iain Matthews also absent and Denny took a additional central role. Unhalfbricking was produced by Joe Boyd, who had signed Fairport Convention to his Witchseason rota of artists.

He provided them with access to a trove of unrecorded songs on paper by Bob Dylan (another input influence of Denny's) that were detained at the offices of Dylan's British publishers, Feldman's.
