I haven’t watched that video yet. But there is an amazing one of him conducting the choral finale to Mahler’s second. It is just awesome as he envelops himself in the emotionally charged music. He brings the listener along with him. Truly amazing.
And as you note: what would the status of Mahler be without LB? Probably still waiting to be re-discovered and that would be tragic.
I am a student (by avocation) of Fritz Reiner, his story, and his music. Maybe because I was getting into concerted music when he was Music Director in my home town.
I find it slightly ironic that Lenny was one of Fritz’s star conducting pupils when they were at the Curtis Institute, because their conducting styles were almost diametrically opposite.
