The good news: Ann and Nancy Wilson both still have their pipes! They have to work harder to hit the highest notes, but it's working. Ann can still pin you to the wall when she rears back and punches it. Nancy's guitar work is solid, and she's really active moving around the stage. They both appear to be in good health and they're punching it out.
It looks like both of them are really enjoying what they do - and what more can one ask, other than the opportunity to do it?
Nancy was wearing the same outfit as in the photo from a recent show below - Ann was in all black with fringe.
The bad: there was a band from Boulder called The Bandits as warm-up. Not a complimentary pairing, as they were "heavy rock" on the edge of metal. Why book a band like that for an audience of 30+ people? No one in the area where I sat could figure out what they were doing there, but fortunately they only played for a half-hour. It was one of those "Well, I suppose it's OK if you like that sort of music..." moments.
Heart only played for an hour, but then they did three numbers in encore - two of them Led Zep. I know they've been doing Zep, and Ann's voice is a darn good match for the old Zep sound. I saw a clip from a recently Kennedy Center broadcast where the band played Stairway To Heaven with Ann doing the vocals - it was DARN good!
