For 40 years now The Manhattan Transfer have been fascinating with the harmony of their voices, with the love in their special and adorable interpretations of great jazz standards. At this moment of celebration, Jazz FM's Svetoslav Nikolov talked with Alan Paul – one of the four vocals in the quartet, about the greatness of the success they have enjoyed ever since their debut 1975 album. The road they walked, the harmonies they symbolize, their connection with Bulgaria are explored on the interview that you can listen to here. Jazz FM's listeners were the first to get a preview into The Manhattan Transfer's forthcoming album.
