This is truly fantastic news!!
I am thrilled beyond words about FM's upcoming tour. But I feared that Christine's unexpected return would sidetrack Stevie from recording any solo work for the foreseeable future. Regardless of whether her solo project gets released this summer, or after the band's tour, we're looking at the possibility of both a SN and FM album within the next 12-18 months. And that's more than I ever would have hoped for.
On a related note, my understanding has been that Stevie has one album remaining on her WB contract. But an anonymous poster on fleetwoodmacnews.com referenced some rumors that she had resigned a new contract, requiring both a new studio album and yet another greatest hits compilation. Regardless, I'm excited to find out what's in the pipeline.
