Bundling acts together for summer tours doesn’t just provide entertainment value, it also allows fans of one act to be introduced (or reintroduced) to acts they might otherwise not have bought a ticket for — and being pleasantly surprised as a result.

At first look, the Americana stardom of critics’ favorite Jason Isbell might not need a second act to bolster sales. Indeed, he’s drawn large crowds on his own across the country — including Wolf Trap, just last fall, where this month he was back again for two nights. 

Yet for all his success, he hasn’t had a fraction of the radio play, sales or widespread pop dominance of Sheryl Crow — whose fans in turn may or may not be aware of his deft songs. Sharing a bill on a tremendous summer night at the wooded Virginia venue and showed how much they have in common, with great bands and sharp songwriting. 

Fans of Isbell would be reminded how many of Crow’s songs they already knew by heart and may have forgotten; and those who came for her hits were open and fair minded enough to hear what the fuss about Isbell was all about, maybe for the first time.
