I love MOS.
It has an expected chord progression, nothing standard.
The vocals start on an unexpected part of the progression, and it's a real slap in the face (lyrics are jarring, the way it is sung is like getting hit by a truck).
Great Edge solo, a bit Gilmouresque.
But I'm not sure if I see it as prog? We have verse/verse/chorus (repeat). We have a solo but I don't think it's out of the standard rock structure.
I'm not trying to be an asshole, just interested in the topic and olen to getting schooled.
School me, baby.
