How legendary is Fleetwood Mac?

[BombaySapphire3]

I think that one thing that Fleetwood Mac did not share with some of the other bands the OP mentioned like Pink Floyd and The Rolling Stones is a consistency of true classic albums over a long period of time.The band had three albums of their classic lineup before their chemistry fragmented.I understand that there were good albums before and after the 'white ' album Rumours and Tusk .I would also include Bella Donna in that rarified group .Here in the states the great Peter Green singles barely registered while Mirage and the inernational smash Tango were able to recapture some of the shimmer of the 1975-1979 trinity the band's fragile chemistry that made those three albums one of the greatest 8 sides of vinyl in rock history had fragmented.Tusk IMHO their greatest artistic triumph was the sound of the splintering of that chemistry.I always wonder what could have been if the band had held it together and made a few more albums without the solo album turkey shoot that prematurely sapped their creativity as a unit.
