Periodically, a pairing of two acts with their own (very) unique identities produces an electrifying musical force that is even greater than the impressive sum of its parts.

As a trio, Gigspanner, formed by (ex-Steeleye Span) legendary fiddle player Peter Knight, has built a massive reputation for dismantling traditional music and song and "reshaping it in fascinating ways".

BBC Folk Award winners (Best Duo) Phillip Henry and Hannah Martin are described by The Guardian as being "Subtle, bravely original...a combination of virtuosity, intensity and charisma".

Their appearances together as the Gigspanner Big Band are a rare but highly sought after affair, thanks to performances of dazzling musicianship and arresting chemistry.

The special double bill is augmented by the exciting new duo of Peter Knight and John Spiers (ex-Bellowhead).
