Paul Miles gave a pretty good blues guitar performance to Ann Arborites on Liberty Street for several hours leading up to a BB King concert at Michigan Theater Sunday night. While Laith Al-Saadi was in the theater opening up for BB, Miles was playing is own opening act – street style. Upbeat slide guitar and lots of smiles. “That’s what it’s all about. They just wanna have a good time,” Paul said. “Peace and Blues.”
