I wholeheartedly agree. In truth, there's much to admire about this recording in terms of performance quality and clarity, but it feels like a non-event to me. That may just be a personal or subjective take.
The only other recording that gives us this much clarity is Boulez's M8 on DG. That one still remains one of my personal favorites, and it would be my top choice if the very ending were more visceral (where are those tams?). And interestingly enough, the Boulez is 10 minutes longer than Dudamel's!
In some ways the Dudamel M8 and Boulez M8 are quite comparable, but what I think tends to work so well with Boulez's is that he takes his time and stops to "smell the flowers," and Dudamel just doesn't do that here. I don't think a quicker overall duration is necessarily to blame either; I think it's all about phrasing. Not to say Dudamel doesn't know the work: we've all seen his Venezuela M8 on DVD... amazing! But not everyone is at their best every time, and this was a live event. Same goes with Boulez: his studio M2 is detailed but a bit bland, and his live DVD is fantastic.
You really never know what you're going to get. In some ways this recording sounds like what Boulez would release, and Boulez's sounds like what Dudamel would release.
LA sounds amazing, the sound quality is (mostly) phenomenal, and Dudamel is a competent conductor in general. I just don't think this particular event was worth putting on disc. Or digital. Whatever medium we listen to these days.
