Didn’t Detect That One Coming: Baltimore club Sonar, a hangout for lovers of alternative dance music and death metal, abruptly shut down yesterday following a dispute between its owners. Sonar staff made the announcement on Facebook: “We here at Sonar regret to inform you that we are no longer able to operate as a venue. Mr. Lonnie Fisher, corporate owner of Sonar, has shut the building down. He has refused to renew the liquor license and the corporate charter for 407 Saratoga Inc.” But Fisher told the Baltimore Business Journal he hasn’t owned the club since 2009, and he’s been trying to transfer the liquor license and charter to someone else for a while now. “I was lenient for all these years because I did not want to destroy the baby I created, but unfortunately, enough is enough,” he says.

More Excuses to Drink Today: If you don’t already have plans to slug margaritas in celebration of a Mexican holiday whose history most Americans probably don’t understand, here’s an alternative: Today is Raheem DeVaughn Day. The R&B singer, a community role model when he’s not simulating sex on camera, is being honored by Mayor Vince Gray for his volunteer work in D.C. (It’s also his birthday.) The mayor will hand DeVaughn a key to the city in a ceremony in front of the Wilson Building at 3 p.m.

Accolades: TBD and former Washington City Paper arts reporter Maura Judkis has been named a fellow of the NEA Institute in Theater and Musical Theater. City Paper (and sometimes TBD) contribitor Chris Klimek, who was a fellow in 2009, gives TBD the lowdown on what this means. Hint: It sometimes involves getting flagellated by Ann Powers.

A Friendly Visit From the Empire: Prince Charles was in D.C. yesterday, speaking at Georgetown University’s Future of Food conference and scoping out the Common Good urban garden in LeDroit Park, and generally disappointing residents who would have preferred to see the Obamas.
