*A tour of New Orleans musicians under the banner of the HBO show “Treme” have booked nine dates this summer, and the promoter is looking to extend its routing into the spring of 2012, Billboard reports.

“A Night in Treme” is booked June 10-13 in San Francisco, Los Angeles, Chicago and Washington, D.C., and will be playing a few festivals in July, August and September. Ann Arbor, Mich., Atlanta, Portland, Ore., and Seattle are likely early stops.

The primary participants in the show – Kermit Ruffins, Rebirth Brass Band, Donald Harrison – have been featured in the series, which starts its second season on Apr. 24.

“Treme” star Wendell Pierce, who portrays trombonist Antoine Batiste, will record a spoken-word piece that details the history of Treme, a musically rich neighborhood in New Orleans. He will appear in person at some gigs to present the informational portion of the show.

“In a way, the show is like Jell-O — it’s a little slippery, not completely solid in formation,” Treme tour promoter Danny Melnick of Absolutely Live says about the revolving cast that will appear on “Night in Treme” bills. “Each date is unique to itself. It’s a night of education and entertainment that tries to make sure people understand the history, understand New Orleans and what it means to the world and that people should go to New Orleans to hear more of this music.

“The idea is that we do this without preaching. The Rebirth Brass Band is there to party.”
