Most beautiful devotional music, and I was never in the movement, but they had beautiful albums, this is one of them. Called "Gurudeva Harmonie" in French, I still have the tape, getting old, I listen to a copy I made often. From Italian devotees.
I also bought this tape in the 80s. I still have the cover but have misplaced the tape. Would love to have a copy of it. Songs of Harmony, Srila Gurudeva. It was recorded with the orchestra of the theater, Scala of Milan, in 1984.
