I have committed another YouTube Video:
Arguably, one of the most consequential symphonic concerts of the last century took place on the 20th of March, 1959, in London's Royal Albert Hall, when the legendary Jascha Horenstein led the London Symphony Orchestra (among many others) in Gustav Mahler's Eighth Symphony - the so-called "Symphony of a Thousand" (because of the number of performers required to do it justice).
It was an event that did much to kick-start the great revival of Mahler's reputation in the 1960's. You can read the whole story here.
For many years, it was believed that either the BBC had not bothered to tape the performance, or that the tape had been lost. But, recently, it turned out that they had not only taped it, but that they had done so in remarkably good stereo sound. Highly recommended.
My video covers about the last six minutes of the performance - i.e., Mahler's setting of the "Chorus Mysticus" that concludes the second part of Goethe's Faust, and the (understandably) rather overwhelming audience response.
Enjoy, if you can.
P.S.: my English paraphrase of Goethe's text (at 4:44 and following) is a deliberate travesty - so don't think I don't know.
P.P.S.: if you've got a broad-band connection, be sure to go to YouTube and click on "watch in high quality." Sight and sound both much improved.
