In the final moments of the third act of Bizet’s Carmen at the Met, the freewheeling gypsy daydreams about her future lover Escamillo as he croons a reprise of his “Toreador Song” from offstage. But then she’s rudely jolted back to reality when the leader of her smuggler gang shoves a heavy bundle of contraband at her. Grimly shouldering the load, she trudges up the mountain pass.
