Week ahead: DMV hip-hop supergroup Diamond District at Black Cat; brighten your summer with Best Coast

Local standouts Diamond District performs at the Black Cat on Friday.

If you go to one concert this week, make it: DMV hip-hop supergroup Diamond District at the Black Cat on Friday Saturday night. The trio of XO, YU and Oddisee have produced some of the best mixtapes to come out of the area and their powers are only greater when they join forces.

If you buy one album tomorrow, make it: “Crazy For You,” the equally sappy, catchy, idiotic and wonderful debut album from indie-pop summer star Best Coast. Be sure to check the review from Chris Richards on the blog Tuesday morning.

And if you stay up late to watch one artist on TV this week, make it: Of Montreal with special guest Solange Knowles Thursday on “Jimmy Fallon.” The reigning spectacle kings of indie rock team with Solange for “Sex Karma,” from the band’s upcoming album, “False Priest.”
