Karen Street Quartet Few accordionists have made their mark in jazz, so Karen Street is a member of a rare breed. A striking musical partnership with guitarist Fred T Baker is refreshed by the addition of award winning jazz singer Sara Colman, along with the talented bassist Andy Hamill. Karen's music is influenced by her incredibly colourful and varied musical past which, saw her grace the cover of the Sunday Times Magazine and star in a BBC TV special to more recently touring with Strictly Come Dancing Live.
