Waterson:Carthy Biography (Wikipedia)
Waterson–Carthy (stylised as Waterson:Carthy) are an English folk group originally comprising Norma Waterson on vocals, her husband Martin Carthy on guitar and vocals and their daughter Eliza Carthy on fiddle and vocals.
They have a repertoire of predominantly British traditional songs and tunes but also occasionally perform contemporary songs from various sources. Their instrumentation is based largely around Martin Carthy's guitar, Eliza Carthy's fiddle and the melodeons of Saul Rose (1996–2000 and 2007-date) and Tim Van Eyken (2000–2007) with other instruments regularly augmenting their recordings. The group also continue the strong unaccompanied vocal tradition established by Norma and Martin's previous family group The Watersons, from whom they are widely considered to have evolved.
The group's first album Waterson:Carthy (1994) was performed largely as a trio, with notable contributions from Eliza's musical partner Nancy Kerr. Their second album Common Tongue (1996) featured a more diverse selection of guest musicians with significant contributions from melodeon player Saul Rose. Although at this stage Rose was not credited as a full group member he soon became a permanent member of the touring group and was credited as a full group member on the release of their third album Broken Ground (1999).
