Not to take this Brahms thread too far off course (from Rattle), but I have been enjoying the heck out of the Janowski Brahms SACDs with the Pittsburgh Symphony. After reading the Amazon reviews, I expected them to be ridiculously fast. I have not found them to be so at all. Symphony # 2 may strike some as fast (and the 4th movement is faster than usual), but i think I would have become a fan of that symphony sooner than I did if I had always heard it that way.
I think # 4 is the best, really intense, rather like the Carlos Kleiber version. I like all four, and the SACD recordings are thunderous. I can't stop playing them!
Symphony # 1 comes with a stirring recording of the Hayden variations, and # 4 includes some Hungarian dances (though not # 6, my favourite).
