Morning all. Normally my colleague Alex Baca writes the Tuesday roundup, but you’ve got me instead. Not to worry, Baca fans—she’ll be back on roundup duty Thursday.

WaPo‘s Anne Midgette has got the scoop on the Washington National Opera’s lineup for the 2011-12 season. The WNO will open with Tosca in September; other works include Werther and, for the first time at the WNO, Verdi’s Nabucco. Guest performers include “opera’s preeminent dramatic soprano” Deborah Voigt and “the world’s most glamorous opera star” Angela Gheorghiu. What’s with these divas and their taglines?

If you had plans to go to Coachella in April but held off on buying your tickets, well, you’re SOL now. The three-day hipster paradise, with scheduled performers including Arcade Fire, Kanye West, Kings of Leon, and the Strokes, has sold out less than a week after tickets went on sale.

Although, if you’ve already bought your tickets, hopefully you didn’t buy it based solely on the Kings of Leon. (I mean, with the other aforementioned acts, plus acts like Raphael Saadiq, the New Pornographers, Brandon Flowers, Duran Duran, Sleigh Bells, and about a thousand more, of course you didn’t.) They’ve postponed their March tour of Australia and South Africa; drummer Nathan Followil tweeted that following surgery, “My bum wing needs more time to heal.”

TBD offers self-proclaimed “exhaustive coverage” of Snooki‘s appearance at the Washington Auto Show. I guess that’s one way you can tell that this town is hard up for the appearance of actual celebrities.
