Jörg Widmann wrote his cadenzas on Haydn's Cello Concerto No. 1 for the cellist Jan Vogler in 2002. These cadenzas add a virtuoso texture to Haydn's spirited composition. This series, unique in classical music literature, focusses on the tradition of solo cadenzas which has grown over centuries. Cadenzas are presented of well-known classical and romantic instrumental concertos, written by important composers and soloists of our time.
