Is it a play or is it a concert? Does it matter? What it gives you is a blend of both, as Raoul Bhaneja explains how a privileged beige guy fell in love with the blues.
The story form is a bit odd, as Bhaneja mixes his personal history with the history of the blues, talking and singing and playing his harmonica. Divine Brown takes the role of the skeptic, but is uncomfortable acting. Singing is quite a different matter however and she gets many chances to show off her vocal abilities.
Bhaneja’s regular backup blues band are also key to the success of the production. The show ends with a jam session featuring a different blues artist each time. Worth seeing.

This was interesting and fun.
It works better in its concert moments than its play moments and I would shift the emphasis to make it more of a themed concert, less of a play.
