CHARLOTTESVILLE, Va. — Los Campesinos! refuse to do their math homework. Instead they make hyperactive indie-pop songs about awkward dancing and even more awkward romances.

PITTSBURGH — In the wake of a national tour and the digital release of his band’s first album, Tokyo Police Club keyboardist Graham Wright shared the details of the new album and its show in Pittsburgh.

LOS ANGELES — After dropping out of Yale’s musical program, David Longstreth made albums about post-9/11 America, environmentalism and 16th-century Spanish imperialism under the moniker Dirty Projectors. But it wasn’t until he made an album about an empty cassette that he found his most universal theme.

Even though it would eventually become clear to the general public that this concert was a generous gift from the Barack Obama campaign, it’s safe to say that the good senator was far away from most of the crowd’s thoughts as the show began.

The absent exclamation mark! The not-so-subtle Beatles influence! The sorta still emo-ness! Yes, everyone’s favorite Fall Out Boy Jr. is back with its sophomore release, “Pretty.

COLLEGE PARK, Md. — If Jack White wears his influences on his sleeve, the members of Tapes ‘n Tapes have theirs tattooed on their foreheads. Almost begging listeners to judge the album by its cover, Tapes ‘n Tapes intentionally imitates its previous album, “The Loon,” on its latest release, “Walk It Off” — neon Warhol-esque prints and all.
