Nicks or McVie.....

The Buckingham Nicks album was unknown to me as well. Will definitely have to check it out. 

By the way: Many years later Keltner, Tutt, and Scheff also appear on Elvis Costello's King Of America album, to my taste his best.

Love them both, disparate styles or no. Always interesting to me how such different talents integrate so smoothly into the 'sound' of the band. wonderful interplay between members. Do I have a preference? Christine McVie

If I have to pick one, it would be Christine McVie.   I really like her slightly raspy voice, and I love most of her writings in Fleetwood Mac.

Stevie Nicks has probably one of the most unique singing style/voice in rock.   It could be an acquired taste for some people, and I find it to be fatiguing at times.   But she's a fabulous backing vocalist on many of the Fleetwood Mac songs with McVie in the lead.

I'm not dismissing Stevie Nicks at all, and I do really like her voice.  I think having them both together is what made Fleetwood Mac such a successful band.

I saw/heard Buckingham & Nicks live in their local San Jose garage band---Fritz---in the summer of ’68 (the opening act at The Santa Clara County Folk/Rock Festival, the headliner the doors. The Electric Flag preceded the doors, and were a tough---impossible---act to follow). Just another local band, no better or worse than many others.

I didn’t hear of their 1973 debut album, but even if I did I wouldn’t have known they came out of Fritz. For some reason, very few San Jose bands had enough professional aspiration/ambition to make the move to L.A. (or perhaps self-confidence). Lindsey and Stevie did. I’m not certain, but I believe The Doobie Brothers got their Warner Brothers deal without making the move from SJ to LA.
