You hear the horns first, and there’s no question what’s to follow.

The legendary D.C. go-go band Rare Essence made an appearance on NPR’s Tiny Desk Concert series yesterday, filling the room with their infectiously joyful sound.

If the District had an official soundtrack, Rare Essence definitely would be on it. Founded 41 years ago by a handful of middle schoolers, the band is nothing less than a local institution. They are even immortalized in the African American History Museum, where visitors can hear their iconic cover of Ashlee Simpson’s “Pieces Of Me.” The group released their 15th studio album last year.

It’s about time the rest of the country took notice, and it may just. A recent analysis by Forbes shows that appearing in a Tiny Desk concert has even more of an effect for artists than appearing on late night television, traditionally one of the most sought-after ways for musicians to appear before a national audience.

According to Vox, there’s just one rule for making an appearance on the series: “all equipment has to fit behind the desk. No PA system, no elaborate effects rigs, no fancy electronics.” The ten members of Rare Essence managed to cram back there and proceeded to jam out accordingly.

“Everybody feeling great now?” they ask the crowd gathered in Bob Boilen’s office. “Somebody make some noise up in here one more time.” The people in the room oblige; it would be impossible to resist.

Here’s Rare Essence’s schedule for the next few months.
