Pocket it and head to Marvin Center Continental Ballroom Sunday at 7 p.m. for a screening of “Blood Diamond.” Honestly, we’re rather sure that this film speaks as eloquently to the issue of conflict rocks as, say, Kanye West or Lupe Fiasco (everybody knows “Diamonds from Sierra Leone (Remix),” but check out “Conflict Diamonds” to make your head spin). That said, we hear it’s pretty good.

If you have $10

Borrow four more because the circus is in town. Ringling Bros. and Barnum & Bailey Circus comes to Verizon Center today through Sunday, and you really don’t want to miss it. The Hendersons will dance and sing as Mr. Kite flies through the ring … oh wait, wrong show. But, there will be elephants and everybody knows how awesome elephants are. Just beware of the clowns. Not that clowns terrify us or anything.

Note: Tickets are $12 with valid student ID.

If you have $20

Take the red line to the Grosvenor-Strathmore station tonight and wander in to the Music Center at Strathmore for some a capella goodness from Rockapella (see, it’s funny because it sounds like “a capella”.). We haven’t actually heard from these guys since those Folgers commercials a decade or so ago, but come on, they were pretty sweet on “Where in the World is Carmen San Diego?”, right?
