I have not seen Bettye LaVette, but I have seen Ruthie Foster as the opener for another show (solo acoustic, no less). If you have a chance to see a Ruthie Foster show, do it. It will be worth your time. This little lady can really sing, and her cover of “Fruits of My Labor” is very, very good. She’s doing a show of her own in Lancaster, PA in mid-July, and I will definitely be there !
