I do agree with your comments, mahlerei.
I viewed the DVD of the live Philharmonie, Berlin, March 2005 performance at the weekend and I also had warm memories of Boulez and the BBCSO performances many years ago.
I'm inclined to return to the Klaus Tennstedt/LPO performances of Mahler symphonies on CD after attending so many performances at the RFH and a fine Sym 8 on DVD.
Claudio Abbado now has my allegiance on DVD in this repertory but there will always be shelf room for Boulez, too.

I remember buying each instalment of the Tennstedt cycle as it appeared on LP. Very fine performances they were toom although I confess I only have his Mahler 8 on CD and of course the EMI DVD of 1 and 8.
I have always struggled with Boulez in this repertoire but was won over by his Mahler 6 and the songs with Quasthoff and Urmana, both superb in their different ways. His recent Mahler 8 struck me as one of the least satisfying I've ever heard. But then I suppose no one conductor has tackled all of Mahler with equal success.
