You should start with Buckingham/Nicks, the album Stevie and Lindsay were recording at the same time Fleetwood Mac were looking for a way forward, and it got them the job with Fleetwood Mac. It’s been unavailable for many years, I bought a vinyl copy in the late 70’s/early 80’s, only to find it was warped, took it back and the album had been deleted!
A remastered CD with a second CD of outakes and non-album tracks has been released this year, and is really worth having.
As far as Stevie’s solo albums are concerned, I’ve got Bella Donna, Rock A Little and The Wild Heart – Bella Donna has Edge Of Seventeen, Stop Draggin’ My Heart Around, a duet with Tom Petty, and a bunch of other good songs, the other two are pretty decent too.
She’s a great singer, and a great performer too.
