Mario Castelnuovo-Tedesco's Guitar Concerto No.1 in D, Op.99 was completed in 1938 and dedicated to Andres Segovia. It was the first modern guitar concerto, being published and performed just a few months prior to the arrival of Joaquin Rodrigo's Concierto de Aranjuez. Before these two works, the last guitar concerto published was more than 100 years earlier.
