Tristan und Isolde (Bayreuth 1966)

Captured live at the legendary Bayreuth Festival, Karl Böhm's fiery conducting drives this profoundly intense recording of Wagner's tragic masterpiece. Featuring towering vocal performances from Birgit Nilsson and Wolfgang Windgassen, the production eschews traditional lushness in favor of a fast-paced, visceral, and highly dramatic interpretation. It is widely considered one of the most thrilling and sonically magnificent documents of Wagnerian opera ever committed to tape.
