Schubert’s main criteria in music was the search of beauty. He claimed he had watched culture get worse from Rock, so he focused on the beautiful. I think if you take Philippians 4:8 seriously you would understand his stance better. He was very passionate regarding the " least of these", and absolutely had lived an interesting life, and knew his classical better than anyone I have ever met. He also had a great love of Sonny Stitt, so whats not to like.
I think he took it to far, to have such a vocal hatred of rock, but I understood where he came from. I agree with Roxy54, we are all so full of contradictions.
Hopefully the use of past tense is that he is not currently here on audiogon.
