Watch the VPO under Solti with Birgit Nilsson as Salome.
Full nudal frontity, as Archie Bunker would say...
I’m not a big opera fan but Salome is one I pay attention to mainly because of the Biblical and historical context. It always amuses me that the part of Salome is often performed by a 30 or even 40 year old singer/dancer. At time of the dance she might have been as young as 12 certainly not older than 17. As to if she danced nude who knows, she was Herod’s niece so he might not have wanted her displayed to the whole court, but Roman culture (at Herod’s court not the rest of the Jewish world) would have had some influence so maybe.
