I, too, listened last night (on cheap computer speakers). I didn't dislike the performance and might consider buying a recording if released. I liked the brisk tempo of the first movement, yet its sections seemed to be pretty well differentiated by Petrenko (rather than a homogeneous rush). The latter three movements seemed generally more 'typical'. The balance across the orchestra (microphones?) sometimes seemed puzzling (and there was a gong or bell that rang more prominently and dissonantly that I recall in any recording), but I am not going to quibble for a free, one-off broadcast.
Coincidentally, I had listened again to the Vanska/Minnesota M6 earlier in the day. I did not like that recording on my first listen and thought I should give it some time to come at it afresh. I was unaware of the BPO broadcast until later in the day, so I had an unplanned comparison at hand. There certainly there were significant differences, starting with the tempo in the first movements. I also found something disturbingly similar in the second, Andante moderato movement.
When I first listened to the Minnesota M6 a few weeks ago, I immediately noticed a change in the lyrical horn solo. I thought it must have been a mistake or a conductor edit. As an amateur horn player, I have the music and performed it in concert. Well, surprise surprise, the BPO principal horn played it the same way! I checked my music and sampled another recording just to confirm the change. I have to assume that the edition that the Berlin Philharmonic and Minnesota Orchestras are using is not only in the A/S order but has changes within the score, too (for me the horn solo being most notable). Does anybody here know the backstory?
