Considered by both critics and public as one of the greatest tenors of the 20th century, Jussi Björling left behind a vast recorded legacy. Volume 4 in the Naxos Jussi Björling Collection features his final recordings of opera arias for HMV (Tracks 1–9), two of which, Carmen and Cavalleria rusticana, have not previously been available on CD. Also included are his first recordings for RCA Victor, including the five classic tenor-baritone duets made with Robert Merrill in New York. Volume 1 of the series (8.110722) features his complete recordings of opera and operetta in Swedish, Volume 2 (8.110740) a selection of songs in Swedish from 1929–37, while Volume 3 (8.110754) focuses on the opera arias and duets Björling recorded in Stockholm between 1936 and 1944.
