In the seventies, Earl Klugh (who I never heard of at the time) opened for Bob James.
After the concert, the record store was still open, so I bought every Earl Klugh album they had.
His live performances are WAY better than his studio work (which still ain’t shabby!)
A few years back Ledisi opened for Gregory Porter. She was excellent! Funny, warm and told some fun stories. Since I had a VIP package my wife and I posed with her and got some nice pictures (when I posed with her she looked at my wife and said, “Don’t worry. I’ll give him back when I’m through!” She was very sweet and funny!
