Today we have a song for classical guitar very virtuous. The song Capriccio Diabolico, is dedicated to the famous violinist Niccolò Paganini, and was commissioned by the great Segovia to Mario Castelnuovo-Tedesco, Italian composer who wrote many great compositions for guitar. Despite the friendship of the two, the recording of the song of Segovia did not greatly pleased Castelnuovo-German, it seems also a little inaccurate to me. Rather, there are interesting interpretations of Kazuhito Yamashita and David Russell, the first very clean, the second with crystalline arrangements. The choice is yours.
