When the news broke that veteran singer/songwriter Lindsey Buckingham would be visiting the North Charleston Performing Arts Center’s stage during his summer U.S. tour, many local Fleetwood Mac fans probably thought of the band’s 1977 album Rumours. Buckingham’s complex finger-picking guitar style was expressive and fluid on that legendary collection, and it complemented the heartbroken lyrics of the tunes with a folksy flavor. Buckingham has been doing his solo thing for more than 25 years, releasing six solo albums and two live albums along the way, but he’s still best known as one of the main songwriters and vocalists in Fleetwood Mac during the band’s commercial heyday in the late 1970s and early ’80s. Buckingham and his songwriting partner Stevie Nicks joined drummer Mick Fleetwood, bassist John McVie, and keyboardist Christine McVie in Fleetwood Mac in 1974. The group had already assembled nine different lineups in eight years. Buckingham distinguished himself in the band. His voice was recognizable, and his rich guitar style — from the prickly acoustic stuff to full amplified and distorted electric stuff — was unmistakable. His musical vocabulary was broad enough to conjure bits of classic, flamenco, bluegrass, country-blues, and Celtic music within one tune. Buckingham says he plans to play an “intimate one-man show” at the PAC on Saturday night in support of his latest solo collection, Seeds We Sow (Mind Kit/Fontana). He says his set list will include Fleetwood Mac favorites as well.
