Kesha and Macklemore

Turns out that team-up on the wistful/dorky “Good Old Days” was a sign, a harbinger, an omen, for this big summer co-headlining tour dubbed The Adventures of Kesha and Macklemore. Expect both artists to do solo sets, followed by a little spotlight-sharing, followed by swarms of teenagers out front texting their dads to pick them up.
