Out of all the permutations and pairings – both creative and not – among the core Fleetwood Mac quintet, this somehow seems both the unlikeliest and yet it is absolutely bursting with potential. The Mac’s tormented creative guiding force, singer-guitarist Lindsey Buckingham, teamed up with semi-retired, golden-voiced singer-keyboardist Christine McVie to cut a surprise album earlier this year, and now they’ve taken it on the road. And if past Fleetwood Mac history has taught us anything, it’s that nothing ever lasts, so be advised to check out this duo – in a tony theater, no less – while you can.
