Texas, along with Bhutan and NASA (yes NASA) are featured at the annual Smithsonian Folklife Festival, which is held on the National Mall between Congress and the Washington Monument. A wide range of Texas music is featured including country and swing from the likes of Guy Clark and Jody Nix and The Texas Cowboys, Conjuncto from accordionist Mingo Saldivar, gospel from the Jones Family singers, zydeco from C.J. Chenier and older creole style music from Les Amis Creole, Augie Myers, Joe Ely, blues from Texas Johnny Brown (this week thru June 29) and Tutu Jones (next week July 2 through July 6). Also appearing will be Marcia Ball and Tutu Jones. There are two main stages for music at the Texas Exhibit, the Texas Opry House and the Texas Music Hall. It is this latter stage at which I caught Texas Johnny Brown performing today. Brown, who turned 80 in February, remains vigorous and was terrific with his urbane modern blues. He first recorded nearly 60 years ago, toured with Amos Milburn, Junior Parker, wrote Bobby Bland's "Two Steps From the Blues." Roger Wood, author of the essential books on Houston blues and Texas Zydeco was a presenter.
