This is my favorite Wagner opera, I love the Arthurian tales. This is a dream cast for this opera. I don't normally think of Bohm as a Wagnerian, but his conducting on this recording rivals von Karajan. Nilsson has always been the ideal Isolde and Windgassen is in surprising good voice as Tristan. I prefer this recording over the von Karajan version because Ludwig & Tavela are superior to Rosl-Majdan & Hotter. It all depends on your preference. You can't go wrong with either recording.
