Keith Pearson's Coup de Grass Bluegrass! Something a bit different for us at St Neots Folk Club. 'KEITH PEARSON'S COUP DE GRASS' is an exciting mix of all that is great in Bluegrass and in Folk. Their music, which ranges from fast, dazzling banjo, guitar and harmonica solos to ballads of exceptional beauty is just a part of what makes them one of the most popular and sought after acts currently playing the clubs and concert stages.
