Which two albums represent Lindsey's best Fleetwood Mac work?

[On Ice]

Lindsey vocals are also in top shape on Crystal, and despite it being a Stevie song, I think his voice brings something to the song that she never could.

How could I forget Crystal, shoot....

Absolutely the right decision for him to sing lead on Crystal, the album would've been perfect with the inclusion of one more Stevie Lead, Crystal wasn't the song. Sorcerer coulda shouda woulda been a show stopping Fleetwood Mac classic as her white album voice would've nailed the song into orbit and a good complement to Rhiannon as she was way under utilized on the album and that first tour.
