Quercus is a 2013 live album by English folksinger June Tabor, Welsh jazz pianist Huw Warren & English saxophonist Iain Ballamy. It is also the name of the trio project which derived from an earlier collaboration on Tabor's At the Wood's Heart from 2005. Though, Warren has been a pianist and musical director for Tabor since 1988. The recording took place at The Anvil in Basingstoke at the end of a tour in March 2006. Ballamy, who has previously recorded for ECM Records with his experimental jazz duo Food, recalled “the piano was excellent, the acoustics in the hall were good, and nobody coughed.”
