Although he was already an established figure in Mexico City, Manuel Ponce's life was transformed after meeting the guitar virtuoso Andr�s Segovia in 1923. Their subsequent life-long friendship and artistic collaboration started with the sprightly wit and airy playfulness of the Sonata 'Mexicana'. The Third Sonata reveals Ponce's romantic-era roots and his affinity for Chopin, while the Sonata cl�sica is both an homage to Fernando Sor and Mozart's delightful Italian operatic style. The remarkable Sonate romantique is almost like a lost work by Schubert. Peeling aside Segovia's editorial changes, Aleksandr Tsiboulski's performances return as much as possible to Ponce's original manuscripts.
