Along with Fairport Convention, Pentangle is one of the most important bands of the 1960s British folk revival. Drawing on a truly diverse array of sources, Pentangle developed a unique version of folk rock that was both traditional and progressive. The group formed when esteemed solo guitarists Bert Jansch and John Renbourn combined their love of classic American blues and ancient English folk songs with the angelic vocals of Jacqui McShee and the jazz-influenced rhythm section of drummer Terry Cox and bassist Danny Thompson. After breaking up in 1972, they reformed several times with varying line-ups, the most well-known of which playing under the name Jacqui McShee's Pentangle.
