Ensemble Ambrosius is a Finnish chamber music group that plays modern music on baroque instruments. It originated in 1995 when three music students performed music of Frank Zappa at a school concert. They added a fourth member and began touring in 1997, adding original music to their repertoire. They have since increased to eight members and have produced two albums, The Zappa Album, and Metrix, the latter being original compositions blending classical, jazz, and rock. This is the Wonderful German Sofa Track.
