Since childhood, I have regarded Fleetwood Mac as “Stevie Nicks Plus Some Guys in the Background.” Little did I know that Nicks never would have been asked to join the band if she hadn’t been riding the coattails of Lindsey Buckingham’s mind-bending guitar genius. His loyalty reached as far as demanding that he and Nicks, who used to perform as a duo, came as a package deal when he was asked to join Fleetwood Mac. The rest is history. Buckingham shares his ingenuity on Tuesday, Oct. 25, at the Uptown Theatre. 1350 Third St., Napa. 7:30pm. $40–$50. 707.259.0123.
