“Sisters of the Moon” from Fleetwood Mac’s 1982 concert at the Los Angeles Forum is an essential performance by most longtime fans’ standards. “Intense silence” as she walks onto the stage, Stevie channels the spookier elements of “Rhiannon” and “Gold Dust Woman.” With her blond locks teased forward and black chiffon pulled over her head, she transforms from fragile gypsy beggar to high-octane rock and roll ballerina. It’s always sheer excitement to see Stevie so engaged and impassioned in tour-de-force rock mode, but the rest of the band seem to be having a great time, as well. With Lindsey rocking a verse, Christine head-banging at her keyboards, bug-eyed Mick fixated on Stevie’s curious movements, and even the normally-stoic John swinging his bass around a few times, “Sisters of the Moon” remains an unforgettable band moment in the Fleetwood Mac live catalog. It’s been more than 30 years since Fleetwood Mac performed the song in concert, but the anticipation has been building ever Stevie revealed on Thursday at SXSW that a resurrection is approaching on April 4…just in time for Easter. Perfect!
