Witness Maria Callas' mesmerising voice and presence as she made her Paris debut, performing a selection of arias from iconic operas. This historic moment, considered the 'event of the century', was broadcast live across Europe and was the first live broadcast of a concert to TV screens in history. Available for the first time entirely in colour and in 4K Ultra HD - meticulously restored from the recently discovered original 16mm reels and a newly discovered sound source – this is an opportunity to experience this historical performance as never before.
