Buckingham doesn't get enough credit for how his mid-'70s addition transformed Fleetwood Mac, with too much of it flowing to his one-time paramour Stevie Nicks. The band hit their apogee on the new lineup's first three albums together — Fleetwood Mac, Rumours and Tusk — before speeding downhill during the '80s. A tremendous producer who loves to ladle on the layers, Buckingham is an equally gifted pop craftsman and guitarist with an adventurous streak. This latter characteristic is particularly applicable to his latest album, Seeds We Sow. Its raw, largely acoustic home-studio vibe is surprisingly understated, allowing the complexity of his playing and lyrical poignancy to possess the whole stage.
