This Music Minus One pack lets you play along with the orchestra. The concerti are performed two times, first with the violin soloist on the right channel for easy removal by the at-home player. This is to enable the violinist to study the score and listen to an interpretation by a professional performer of the highest skills. The orchestra then performs the concerti again to accompany your own solo performance! Michael Metelka, violin soloist The Czech Symphony Chamber Orchestra, conducted by Mario Klemens
