Griselda Sanderson's main instruments are violin, viola and the nyckelharpa, an unusual bowed keyed fiddle from Sweden. She specialises in folk and traditional music and has a large repertoire of traditional Scottish, Irish and Swedish material.
Griselda has a special interest in North and West African music, which has led to collaborations with musicians Juldeh Camara from The Gambia, Amadou Diagne from Senegal and Simo Lagnawi from Morocco. Recent recordings on her own label Waulk Records are her solo nyckelharpa album Harpaphonics (2008), Traders(2011) under the band name Julaba Kunda with Juldeh Camara, and Yakar, Amadou Diagne's second album (2013). She produced and arranged the strings on the albums, as well as producing a debut album for London-based Moroccan Gnawa master Simo Lagnawi entitled Gnawa London (2013).
Having studied both classical and traditional music she has performed in a wide range of contexts from string quartets and orchestras to acting/playing parts in theatre with the Royal Shakespeare Company and film with British director Mike Figgis.
