How revolted was Tusk?

[Villavic]

Ok, Tusk didn't sound like Rumours. But according to Mick's book, it was like Lindsey wanted to be part of the new 80s sounds, leaving behing the (Rumours) pop sound and the "dinosaur" image of the 70s band. However I don't find an "80s" or "New Wave" groove in Tusk. Yes, Tusk was different than Rumours, but I don't relate Tusk with any of the new bands from that era.
I don't find Tusk as a revolutionary album either. Just different than Rumours.

Lindsey was always listening to the new stuff. On tour in England he went to see the Clash and some of the other new bands. It was like he couldn't stay still when there was this revolution going on. As such, Lindsey wanted to be part of the revolt; when it came time to start work on our next album, Lindsey made it clear that this record was not going to sound anything like Rumours.

Of course, he was right. The old twelve-bar blues of Fleetwood Mac had now completely mutated into the Rumours groove, but that wasn't what we were about either. That was just one epoch in a long history, but suddenly we were being lumbered with the general impression that "this" was Fleetwood Mac. We didn't feel this way, but people around us did. Thankfully, we were still on our own, and were spared having a business cadre whispering "creative" ideas into our ears. We were still in control of our own destinies, with total creative control and almost no outside input. By now, we felt, it was part of our mystique within the industry.

As I've said, Lindsey was fairly disgusted with people's expectations for our next album. He was acutely aware of the New Wave criticism of the so-called dinosaur bands, and wanted desperately to make a contemporary artistic statement in our new album. The musical appeal of Rumours had been no accident. Lindsey and Richard shared a house and spent their "spare" time listening to records, trying to discover what worked and why. They'd pick a hit record the Supremes, or the Beach Boys and spend hours working them out for the mechanics of the sound. Lindsey was now bored with the normal pop framework. He wanted to experiment as much as possible within the context of the band, and this led to some serious discussion between the two of us.
