I made my comment about Rattle being slow because I thought (mistakenly) he was the slowest I own -- here's a random selection I looed at:
Mravinski --10,10
Abbado 10.02
Mengelberg 9,36
Weingartner 9, 42
Kempe (Testament) 10,12
Furtwangler 9,21
Gardiner 9,35
In fact there are three which I own which is longer than Rattle's: Bruno Walters New York (10,50); Max Fiedler's at 10,51, Celibidache's EMI, and Victor "The Tortoise" De Sabata who chalks an astonishing 11,56.
I've not checked everyone I have -- Toscanini and Harnoncourt and Klemperer's EMI are in Marseilles and I'm in London.
