Nicola Benedetti introduces the second of two Proms celebrating the 250th anniversary of Mozart's birth, recorded live at the Royal Albert Hall. The composer's orchestral music is the focus tonight, as celebrated violinist Maxim Vengerov fills the roles of both soloist and conductor. Vengerov leads the Verbier Festival Chamber Orchestra in a programme comprising Violin Concerto No 2, Symphony No 29 in A and Sinfonia Concertante, for which he is joined by the brilliant British violist Lawrence Power.
