Before everyone gets into a tizzy, let's step back, take a breath, and think this through.
1. Although I tend to believe him, Mick is notorius for getting things a little muddled. Stevie doesn't record solo albums this fast, and it's possible she's laying down some basic tracks to work on AFTER the tour (I doubt this).
2. Just because she's recording in Nashville, doesn't mean it is a Country album. Nashville has a diverse music scene. It's more likely that Stevie had planned on going into the studio after the last Mac to record an album (a studio, or her house, in LA). Christine re-joining the Mac put a damper on that. Dave Stewaart simply suggested that he had a studio and crew in Nashville that he knew could fast track recording an album. Stevie has so much faith in Dave that she jumps at the chance to do an album before she ggoes back to the Mac.
