Hi,

I've just noticed this thread, and thought I'd chuck in my two-penneth. Of the CD's I've catalogued so far, here's my longest individual tracks:

"Sadalmelik" by Moljekba Pvlse: 72:16
"Leviathan" by Legion: 71:59
"Envoi In Cumin" by Arcane Device: 71:33
"Soundpooling #3" by Nurse With Wound: 66:42

I also have "Holy Of Holies" by Nocturnal Emissions, a four hour DAT tape. As I never got a DAT player, I cannot verify whether it is one long track (as listed on Discogs), or shorter tracks as on the 4xCDr reissue... The mystery is no doubt far more enticing than the reality could ever hope to be!
