Regazzo has a well-focused warmly timbred bass voice which he is able to project with authority. Furthermore, Regazzo is well able to sustain a dramatic scena such as the mad scene from Orlando furioso… Regazzo is matched throughout by clean, dynamic and sympathetic instrumental playing. This is altogether a fine recital.

The excellent Concerto Italiano under their scholarly conductor Rinaldo Alessandrini play with skill and imagination… Regazzo is a consummate master of the art of expressing through the voice and the voice itself is an exceptionally fine instrument. ...Regazzo has the fine, well rounded tone and evenness of line; his style commands authority, with a nobility of utterance.
