NYC Ghosts hadn't been released yet, so no one had even previously heard anything they played in the first 70 minutes. They played an eight-minute version of Lightnin' (which is basically just fucking about with some instruments) then finally played a pretty ropey version of Sunday and left

Then at some festival in the USA years later they played 30 mins of noise from an early record and got panned for that.
Appreciate the insights and the links as well!
