MGMT + Dinosaur Jr.

The psych-rock outfit returns home to Brooklyn after crisscrossing the country in support of its self-titled third album. The band’s music has gotten grungier and weirder since the platinum-certified days of “Kids,” but the spectacle in its live shows has held strong, promising the kind of strangeness you don’t often see in an arena setting. If that’s not enough to sell you, we’ll point out that the openers—Dinosaur Jr., godfathers of lo-fi rock—are worth the price of admission in their own right.
