I've seen two shows in the last week or so:
The first was "Frampton's Guitar Circus", featuring Peter Frampton as the headliner, with Sonny Landreth and B.B. King as his support acts. Frampton also had a couple of guests during his set- Larry Carlton and Rick Nielsen of Cheap Trick. Peter's son Julian also came out to sing lead on "I Want You to Want Me" and "Surrender" while Nielsen was on stage. Julian has a great voice- sounds a bit like his Dad. "Surrender" was a blast, with most of the crowd singing along.

My only complaint was that I wish Frampton's set was longer- he played for about 90 mins.
B.B. King is really showing his age, and he didn't play too much, but he still managed to entertain the crowd. Frampton guested with him on "The Thrill is Gone":

The other show I saw was Keith Urban in Indianapolis. He also had two support acts- Dustin Lynch, and Little Big Town. Keith puts on a great live show, and he didn't disappoint.

He has a new album out in a couple of weeks, and he's been playing a couple of songs from it- "A little Bit of Everything" and "The Stars Fall For You". I love the lighting designs this tour as well.
Since he was in Indiana, Keith had to play some Mellencamp, so he brought out Larry Crane from Mellencamp's band for "Authority Song":
