My reactions after several months of listening are that the D minor is a very good performance but the B flat is outstanding. I'd have been pleased to hear the First in concert, but ultimately I think it lacks a special quality - the austere authority of Gilels/Jochum, the sinuous strength of Curzon/Szell or the frolicsome fire of Kovacevich/Sawallisch.
But in no. 2 Freire and Chailly capture the breadth of the first movement while keeping it moving, the grip of the second without losing the dance, the repose of the slow movement without falling asleep and the undertow of the finale whilst retaining its life. The result is convincing and compelling. The characteristic Gewandhaus band are a delight throughout, and the recording is well balanced. The documentation is rather thin for a new release, but you can't have everything.
