Carlo Buti, born 1902 in Florence, died 1963 in Montelupo Fiorentino. His voice teacher was the same as Gino Bechi's - Raoul Frazzi. But though Buti made a handful of aria recordings, the realm where he was king was that of Italian song. His popularity in that field was beyond comparison. He is said to have recorded 1574 different songs.
I wish to thank Robert Schlesinger for the recordings (Mattinata, Chitarra romana, Luna marinara) and notes.
