McCartney in 2002 in Denver. Before that I’ll go back to about 1977 and Seals and Crofts. I wasn’t expecting much when I went to the concert, maybe just a couple of their hits and some minor hits. I was really surprised by the show! Their musicianship was far more varied and top-notch. They were known for their soft-pop and hippie music, but they were awesome bluegrass musicians as well. They brought the house down with a raucous country hoe-down (literally, a large bank of speakers came crashing down!)
Another memorable show was Willie K., who played at my wife’s high school reunion in Hawaii. One guy, one guitar, jaw-dropping mayhem! He did Hawaiian, Rock, Opera, Jazz. I’ve never seen or heard anything like it.
