Son nata a lagrimar, from Théâtre des Champs-Elysées production of Handel's opera Giulio Cesare. Duet vocals by Franco Fagioli & Lucile Richardot

This whole performance was incredible, but my favorite songs were this duet (Timestamp 1:10:00) and Se Pietà Di Me Non Senti (Timestamp 2:02:04), sung by Sabine Devieilhe.
