If you've had it with orange, the Riverside paints All Hallow's Eve blue on Friday as legendary blues guitarist and singer B.B. King plays the Downtown theater.

King -- along with his trademark Gibson guitar, named Lucille -- has decades of material to draw from when he performs, but you can be sure that this time 'round he'll focus on his latest disc. "One Kind Favor," produced by T-Bone Burnett, was released in July and on it, King returns to his roots, playing the songs that got him started.

On tunes like "See That My Grave is Kept Clean," "How Many More Years" and "Get These Blues Off Me" -- the titles seem as appropriate as ever for King-- with Dr. John on piano, Jim Keltner on drums, Nathan East on double bass, and a host of others.

In September, King was on hand for the opening of the B.B. King Museum and Delta Interpretive Center in his hometown of Indianola, Miss. Now THAT'S a sign of a living legend.

Don't miss him this week when he turns Brew City into Blue City. Tickets are $45 and $55.
