The present volume is the fourth in a series devoted to Beniamino Gigli’s ‘singles’ – his song and aria recordings not issued as part of complete opera sets. The aim of the series is to include every Gigli recording released at the time, as well as every published alternative take and, wherever available, unpublished takes. The sides here are presented in the order in which they were recorded. For this Naxos series, restoration engineer Mark Obert-Thorn has remastered his original, critically-acclaimed Romophone transfers, cleaning them up further and re-doing some tracks in their entirety. Of special note in this fourth volume are Gigli’s recordings of duets from La bohème and La forza del destino with the baritone Giuseppe De Luca. Their fine-tuned performances are testimony to the two singers’ frequent collaborations at the Metropolitan Opera.
