The Academy Is is not quite a band that has found its way into everyone’s music dictionary. It hasn’t even made it “big” yet, spending most of the summer as the opening act for pop-emo-punk giant Fall Out Boy. In fact, the name of the band’s headlining fall tour, the “Sleeping with Giants Tour,” perfectly describes the band’s ascent to relative popularity.

That said, the “Sleeping with Giants Tour” is coming to the Palladium in Worcester tonight, bringing with it The Academy Is, Armor for Sleep, The Rocket Summer, Sherwood and Cobra Starship. If last Saturday’s show at the Casino Ballroom in Hampton, N.H., was anything like what the rest of the tour will be, this show is certainly a must-see for any fan of pop-rock. The four opening bands are energetic, young and excited to be on the road, and it shows.

After arriving at the venue, one major aspect of the show was immediately noticeable: the median age of the audience was about 14. The first band of the night, Cobra Starship, took the stage without a soundcheck, as is usual for opening acts, and quickly busted through its brief 20-minute set. The second act, Sherwood, from San Luis Obispo, Calif., put on a good show for the limited time it had, but the band seemed too chill for its own good. The group’s particular brand of feel-good.

SoCal easy-rock seemed to hype the crowd, but the band didn’t capitalize on the crowd’s energy. Sherwood did, however, point out that the Pacific Ocean was nicer than the Atlantic. Perhaps these guys are just better on their own turf. The first “real” opener, The Rocket Summer, got more squeals from the audience than a fully nude Pete Wentz before it even hit the stage.
