A Wilco concert is worth getting excited about. So is a My Morning Jacket concert. The idea of the two of them playing together should be a thrill.
But for the Americanarama Festival, Wilco and MMJ are little more than footnotes. That's because the headliner is Bob Dylan, arguably the most important musician of the past half-century.
The festival also features Bob Weir of Grateful Dead fame.
The "Americana" label in the title of the festival is odd since only Wilco is really an Americana band. Dylan and Weir may approach that genre occasionally, but My Morning Jacket, the Kentucky-based outfit known for epic live shows, falls more into the psychedelic soul category. (Other stops on the Americana Festival feature the great Richard Thompson, whose music is firmly based in British folk.)
Wilco's records generally have a folk-country base, but live they often let loose with extended noise jams.
Depending on Dylan's mood, Weir promises to be the most laid-back act of the four.
Dylan is unpredictable in concert, even more so than on records. His live shows generally draw from all periods of his career, with adequate emphasis on the dozens of his songs that have helped shape American culture and music, but he often performs them in stylistically altered form.
He's probably still promoting his latest album, "Tempest," which is getting solid reviews, so it's reasonable to expect a dose of new songs, too.
The Tampa show is only the second on the Americanarama tour (it started in West Palm Beach Wednesday), so there are no reviews, tweets or Facebook posts to let us know exactly what's in store. It's almost sure to be memorable.
