This Blu-Ray series has really seen Chailly take a step away from his earlier recordings. This ninth is, in my opinion, is further from his earlier recordings, than any of the other installments. In the included documentary with De Le Grange, they speak of having of getting away from the, "self-indulgence and slow tempos of the past." Chailly also speaks of going back to the Mengelberg scores, he's done this in all the docs, and this time he really disagrees with Mengelbergs intentions with the score. DLG and Chailly also spend a bit of time speaking on how this work always gets associated with death, and Mahler knowing he was dying. Both were of the opinion that this is more a work about life, and should not be the this romanticized, lush, and sad piece of music. The doc is excellent to watch, it's like two buddies sitting down and just talking.
The concert itself very much reflects what was talked about in the documentary. Tempos are quick, it's quite lean and highly detailed. The climaxes are very well paced, the third in the 1st movement is very impressive. Phrasing is very exact, nothing is stretched out, or lingered upon. The Landler is one of the quickest I've come across, as is the Scherzo which gets quite raunchy. Very well played and full of life. The finale is very optimistic and uplifting, he doesn't even milk the last the notes. Taken as a whole this concert gives a very different feeling and is quite powerful. I also think some may not like what Chailly is going for.
