Arlington — On Friday, May 18, an immense display of synchronized drumbeats and vibrant rhythms performed by Batala Washington hailed the grand opening of Artomatic 2012.

Forty all-female members drummed the signature Brazilian-reggae-samba tunes of Giba GonÁalves, who created the international Batala groups in 1997. The Washington, D.C. chapter is one of 23 ensembles that perform worldwide.

“We’re very excited to play at Artomatic, we’re really amped,” said conductor Ellen Arnold Losey. “A lot of the women joined after hearing us the last time we played at Artomatic in 2009.”

Many in the audience were keen to take up the offer. “It was fantastic, I want to join now,” said Alexandria native Arden Colley. “It was worth coming out just to see that.”

This year’s Artomatic boasts 1,300 artists in the largest location to date for the D.C. area’s chief artistic event — the 11 stories of 1851 S. Bell St. in Crystal City.

“This is by far the biggest and best Artomatic ever, the energy is just vibrant,” said Angela Fox, president and CEO of the Crystal City Business Improvement District. “The message is clear: Crystal City is at a new playing field.”

Unlike in years past, the Crystal City location does not have walls separating installations. The result is an array of amateur and professional work placed side-by-side.

The extent of this year’s Artomatic, however, means visitors will have to return multiple times to catch it all. Fox estimates that as many as 100,000 people will visit before the June 23 closing.

“It’s fun and fabulous and wild out there,” said Fox. “Expect the unexpected and make time to explore.”
