Got a few:

Bonnie Raitt with Lyle Lovett: she was phenomenal and Lyle opened for her then joined her for an encore that lasted quite a while. [br][br]

Joan Armatrading: her guitar playing is not widely recognized, but she can cover folk, blues, jazz, and rock. Energetic entertainer and funny as hell!

Jackson Browne: great player, knows how to engage the audience and it was a fun concert.
