"Tusk" and "Metal Machine Music"

Philco Bros. weighs in on the great "Tusk" question:

I'm not sure the actual song is advanced but the idea of releasing it as a single after the major success of the previoius two LP's is very Metal Machine Music-like.

Excellent point. I'm now thinking that the album might qualify as an Advanced Irritant. In fact, I'm sure of it. And I think that Lindsey Buckingham was probably the driving force behind it. He is, by the way, one of my favorite guitarists with large brown hair (Brian May and Mike Campbell are the others).
