This review is based only on the performances as I have not yet seen the supplementary material. When I first started to watch/hear this bluray I was disappointed as the tempos seemed slow, very different from the energetic ones that recent `authentic' instrument versions have provided us. And Theilemann's presence on the podium lacked charisma and his manner is stodgy and eccentric compared to the aristocratic ease of Karajan or the electric energy and `sex appeal' of Carlos Kleiber.
I was reminded of Otto Klemperer's ponderous tempos and also his comment to a frustrated record producer named Walter Legge that he (Legge) would soon get used to the tempos. Within minutes of this disc, I `got used' to Thielemann's tempos, and though the sound he produces is not like Klemperer's (who had a different orchestra and a unique way with clarinets) it is very satisfying. I have the laserdisc of Kleiber's 4th and 7th symphonies and I find Thielemann's 7th to be as satisfying in its own way. He is slower in the first two movements but speeds up in the last 2. A tempo speedup in the middle of the final movement of the Choral Symphony also surprises but all in all, these performances in crystal clear image and sound, are so good, I have ordered the other 2 blu-rays with the remaining symphonies as well.
The 9th symphony is rendered as magnificently as I have ever heard, with every movement given its due - unlike many others which excel in this or that movement but don't provide a consistent whole. With this bluray, I was unable to 'fast forward' to the next movement - compelled to let the music flow, and this was true of all the symphonies. I have plenty of Beethoven sets - Harnoncourt, Gardiner, Abbado, Zinman, Karajan '62 and '77, Vanska on SACD, Klemperer, Schmidt-Isserstedt, Masur, Bernstein on LP, Haitink on Concertgebouw and LSO Live sacd, etc., and this bluray is as good as any of them.
I don't think I could listen to any period-instrument set after this, except the Harnoncourt which has unique delights.
