It would help you pass the time, until you could escape from the deserted island situation.
Yes JH, in that certain situation I hope I will be in some tropical beach, like these in the travel commercials.
So there i will not want to be in suicidal mood so no M9 or M6. But i can't be without the numerous nostalgic Adagios. So a combination of M2 movement ii, M3 finale, M4 mov.iii, M5 Adagietto, M6 Andante will be very pleased to me.Also, this way I could dream of Alpine highs and meadows, which will be so far away.
But for my desert island in real life( i mean,my home), I will choose M9, Bernstein, Abbado or Giulini conducted. ( Haven't hear yet a lot of M9 a pocess. Among them Macal, Kobayashi, Rattle both,Barenboim, Sinopoli Dresden, a lot of live Haitink, Ozawa, Maazel etc. You see I want time to absorb any performance, and I don't listen too often the works I like a lot, so not to burn them out.)
