The math of summer tours can make for strange bedfellows. If you want to sell a venue like The Pavilion, you need a bill that will pull in enough people to justify the space while still making some sort of musical sense. Incubus and Jimmy Eat World do not immediately come to mind as natural tour-mates, but as survivors of early-’00s rock radio, it makes a kind of sense. Both have buckets of hits while also having new records to support, both leaned closer to the softer side of rock radio and both know how to put on winning performances. Hell, “Drive” and “The Middle” are cut from the same “Don’t Stop Believin’” cloth. The bill gets an energy boost from newcomers Judah and the Lion, who, like their music or not, leave it all on the stage every time they perform.
