The longest track I've ever listened to

What is the longest track you've ever listened to?
My "best" are from Earth, Sunn O))), Darkestrah - more than 30 minutes. The best I can remember is Sunn O)))'s Helio)))sophist - 48:17.
I've once listened to a track that was about 65 minutes, but can't remember which track it was :)
But, in generall, the "worst" relations length/track account are in classical music - symphonies, piano concertos/sonatas for example (Ludwig van Beethoven, Dmitri Schostakovich, Sergei Rachmaninoff), etc.

Forbidden Fields - Field I - Night (77:35)

My longest so far is Ryo by Kawabata Makoto, if i remember correctly. (67:48)

but i just checked and Delirium Cordia by Fantomas is longer (74:12)

Either Erol Alkan's Beyond The Wizard's Sleeve Re-Animations (which although available as seperate tracks I have as one track on my ipod) or 45:33.
Beyond the Wizard's Sleeve is just under an hour and LCD's 45:33 is 45 mins 58 seconds.

OK, I already know why. But still, this is incredible :)

Yes, I see :) 117 GB :-X Have you ever listened to the whole track (without breaks) :) ;)?

Jean-Michel Jarre - En Attendant Cousteau (47 min)
Sunn O))) - Helio)))sophist (48 min)

Don't remember any longer Tracks.

Trist - Hin

Nadja- thaumogenesis 1:01:44

Robert Rich - Somnium Part 1 is 270 minutes long. The whole album, a continuous piece, is over 7 hours long

Yeah, OK, PirtePiraja, do you think, that this composition "As Slow As Possible" is really a music piece? Look, if I have my computer on, and "listen" the whole day to the "sound" which the cooling makes, I could say it is "a very slow music of my computer", what do you think? Maybe tomorrow I will work with my notebook, which has a cooling that makes some another "tone" - but in fact, I can't remember the "tone" of my computer's cooling, I can't get any rhytm (which is very importnat when listening to music), any melody (ok, not every composition has a melody) etc.
In fact, I could take any piece of music - let's say some Wagner's opera (they are pretty long, too) and tell the musicians to play it as slow as possible, and I get for example a 25-years-long piece.
And, by the way, my question was: what is the longest track you've ever LISTENED TO. So - have you listened to the whole John Cage's composition? :)
I don't want to argue, just thinking of the whole thing...

It *is* actually interesting to think what qualifies as music, what we accept as music, about the restrictions of the media (Rich's Somnium is on an audio DVD, as I just found out) and the limitations of our attentiveness and stamina. Does there have to be *a* listener in order that there is music? I guess Cage's 639-year composition may have "rhythm and melody", but on a monstrous scale... If our definition of music depends on rhythm and melody, as we are accustomed to observe them, a lot of modern experimental music does not qualify as music; "musique concrète", for example.

I personally do enjoy rhythm and melody – been listening mostly to reggae (ska, dub, roots) for quite a few weeks now. And I must confess I am not a big fan of John Cage's music, even though his *ideas* are interesting.
