I heard the Resurrection with Dudamel and the Bolìvar Orchestra at the 2008 Lucerne Festival. While it didn't lack some spectacular moments (but which performance doesn't?), I found Dudamel's architectural grasp of the whole pretty much equal to 0. It was just a sequence of schyzophrenic gear changes which made me think more on Mussorgsky's Pictures at an Exhibition than on a Mahler Symphony (keep in mind I love Bernstein, thus I'm not against taking some unusual ways). Imho he still is quite far away to really get in touch with Mahler (and with many other composers which require some architectural grasp...thx God he hasn't thrown himself into Buckner yet), spectacular and brilliant doesn't necessarily mean great. So far, a recent quite nice Alpensymphonie apart (at Lucerne), Dudamel always failed to particulary impress me.
As for this performance, it sounds very similar to Dudamel's at the point I wonder if the conductor actually was rehearsing it for him. I prefer this one to Dudamel's, but it failes to impress me as a whole although surely sounding spectacular on some places.
At this point I really can't decide wether this sudden Venenzuela hype is due to real qualities or (at least partially) to some wise marketing strategy.
