Stevie Nicks holding up Fleetwood Mac's new album

Mick Fleetwood has spoken out about the reason there hasn't been a completed album since 2003's Say You Will. He has said that it all comes down to Stevie Nicks.
 
Mr Fleetwood said to Rolling Stone that Fleetwood Mac have completed 'a huge amount of recorded music' but 'none of it's with Stevie. or very little. Some of it is very, very old stuff that Lndsey [Buckingham] maybe did with her years and years ago. We're not quite sure what will happen with it'
 
The band also blamed Stevie for their long delayed Fleetwood Mac tour, saying that she was too obsessed with pursuing her solo career.
 
When Christine McVie‘s returned to the band, it led to a huge influx of new material. “I do know that when Christine came back, she came back with a bag full of goods,” Fleetwood added. “She f—ing wrote up a storm. She and Lindsey could probably have a mighty strong duet album if they want. In truth, I hope it will come to more than that. … There really are dozens of songs. And they’re really good. And so you think, “S—, I don’t want it to be that, decades later, when we’re all pushing up daisies, someone hears this stuff and goes, ‘Well, that should have come out!'” So we’ll see.”
