Bert Jansch is widely acknowledged as one of the most influential songwriters and guitarists of all time.

A leading light of the 1960s British folk revival and a founding member of folk jazz supergroup Pentangle, his career spanned five decades, inspiring generations of musicians with his groundbreaking acoustic guitar technique and emotive songs.

A stellar line-up including his friends, fans and collaborators celebrate his extraordinary musical legacy in this concert marking what would have been his 80th birthday.

The artists playing include Bernard Butler and Sam Lee; Brigid Mae Power and Steve Gunn; Pentangle’s Jacqui McShee, Mike Piggott and Kevin Dempsey; James Yorkston and Ranjana Ghatak; Kathryn Williams; Martin Simpson; Robert Plant’s Saving Grace; and Sarathy Korwar.

Jansch had a long history of performing at the Royal Festival Hall: Pentangle’s first major performance took place here in 1967 and they recorded part of their Sweet Child album here in 1968.

The original Pentangle line-up reformed to play the same hall exactly 40 years later and it was a Pentangle show at the Royal Festival Hall in August 2011 that proved to be his last performance.
