Did he enjoy the Mahler? I don't see the Berg concerto being that much harder on the ears. Probably one of the most accessible compositions to come out of the Second Viennese School.
What's really funny is that he asked if it was the same music we had heard conducted by Rattle, admittedly because he read the notes and they used the same ones from the Rattle concert. When I said that it was the same music, he replied that now he understood why I was complaining so much back then. This was a much more lively and dynamic performance. I would love to hear what Eschenbach could accomplish with those virtuoso Berliners; certainly more than the mishmash that Rattle is creating.
