In commemoration of the 400th anniversary of the death of Miguel de Cervantes, La Ritirata and Josetxu Obregon have created a program for Glossa sallying forth on the back of music composed by Antonio Caldara and inspired by El ingenioso hidalgo Don Quijote de la Manch. Antonio Caldara was neither the first nor the last composer to have his compositional ingenuity sparked off by Cervantes' timeless masterpiece. Interspersed between these vocal contributions are a series of instrumental ballets composed for these operas.
