I first (and last) time I saw Fleetwood Mac was in 1981 at Wembley Stadium in London. Now they are coming to Des Moines’ Wells Fargo Arena – on June 26, 2013 – and I don’t think I’ll be there. The tickets are too expensive and I’m not a huge-venue music-going gal any more (if I ever was.) But it’s funny because we thought of Stevie Nicks a week ago when we were watching Grace Potter perform (at a much smaller Des Moines venue, Hoyt Sherman). Potter has some Nicks-esque moves – as many of today’s’ young female rockers do. (Potter also reminded us at times of Grace Slick.) Right now I’m listening to the wonderful bluesy singer Trixie Whitley (we used to listen to her dad Chris, who sadly died young). The closest she’s getting into Des Moines, for now, is Feb. 12 in chicago at Schuba’s….
