This fall, Fleetwood Mac begins the next phase of their career when a new lineup hits for a road for an extensive tour. Longtime members Mick Fleetwood, John McVie, Stevie Nicks and Christine McVie will be joined by newcomers Mike Campbell and Neil Finn. Mick Fleetwood discussed the departure of Lindsey Buckingham and the upcoming tour as part of a new interview with Billboard.

The drummer spoke with Billboard on Saturday at the Sunset Marquis Hotel in Los Angeles about his photography, a partnership with Morrison Hotel Gallery and this fall’s Fleetwood Mac Tour. When asked about the upcoming run, Mick responded, “We’re very excited. Obviously this is a huge change with the advent of Lindsey Buckingham not being a part of Fleetwood Mac. We all wish him well and all the rest of it.” Fleetwood went on to share, “In truthful language, we just weren’t happy. And I’ll leave it at that in terms of the dynamic. And he’s going out on the road more or less the same time I think — not in the same places, I hope (laughs).”

Here’s more of what Mick Fleetwood had to say about the upcoming tour:

So we’re with Mike Campbell from Tom Petty and Neil Finn from Crowded House — both really credible gentleman and really talented. We are a week into rehearsals and it’s going really well and we’re looking forward, in true Fleetwood Mac style. If you know anything about the history of this band, it’s sort of peppered with this type of dramatic stuff. It’s a strange band really. It’s ironic that we have a 50-year package coming out with all the old blues stuff with Peter Green, all the incarnations of Fleetwood Mac, which was not of course planned. But that’s what we’re feeling, especially myself and John, having been in Fleetwood Mac for 55 years. So it’s exciting, totally challenging in the whole creative part of it, and we’re really loving it. We’re just looking at a whole 18 months on-and-off of trekking around the world like we normally do and having it be fun.

Fleetwood Mac begins the tour in Tulsa, Oklahoma on October 3. The tour is currently set to conclude in April, but as per Mick will run a total of 18 months. Head to Billboard to read about from Mick Fleetwood.
