Here's the "Windowpane" video. It is strange... not many people on this board seem to know it even exists, but it was the first one that actually got any airplay.
Opeth always do things that we, the fans, don't expect, so this may happen.but, we have already expected it, so it won't happen,and we expected that this won't happen, so it will happen.....and the loop goes on
Videos for songs off older albums have been done before, but as I said it's pretty rare. It's usually done for artists that started off small and grew super huge after a few albums... a level of fame Opeth will probably never have seems like a prerequisite.
The "Windowpane" video isn't bad by any stretch, but I think the video for "Harvest" is better, especially the bits of them laughing it up and screwing around.
