I usually like Petrenko, but 'good grief' - did you listen to the "Purgatorio"? After a huge increase in tempo, he then makes a MASSIVE ritardando that almost brings the music to a complete halt. If you want to make huge contrasts, one ought to augment the orchestration instead (I have several ideas).
The second scherzo is pretty good, but I don't like the ultra-slow tempo for all that string heavy, "I love you, Alma" music that comes after the reprise of the first movement's harrowing, expressionistic climax in the finale. I like how Gianandrea Noseda pushes all that music forward in his Chandos recording. It's not a redux of the finale to M9 - just the opposite, really.
All in all, still a good performance. I thought the transition from the fourth movement into the finale was very well handled.
