Fleetwood Mac became an entirely new, and in my opinion much better band, when they reset in 1974. This lineup produced two #1 albums with Rumours at #1 for 31 weeks and it became the 8th top selling album to date. I liked them before the reset but I cannot argue with success and I really loved both of those albums. So yeah, I'd say Fleetwood Mac 2.0 was def an upgrade!
