The warmth of a D.C. summer doesn't just come from the high temperatures. It radiates from the wide array of concert series presented every year, bringing people together at city landmarks to celebrate the season in a way that only live music can. The best part is, not only are these concerts typically high-energy, but they also come at no cost.
Two of this week's best picks triumphantly carry a little bit of New Orleans flavor with them as they play in the District this week:

The Revivalists
After Hurricane Katrina destroyed the physical foundations of New Orleans, Tipitina's Foundation sought to preserve the remaining, distinct cultural foundation. They did this through Sunday workshops breeding young musicians, which brought together guitarist Zach Feinberg and drummer Andrew Campanelli. The end result, less than two years old, fuses rock with reggae and funk, plus a heavy dose of soul through David Shaw's vocals. But all the same, they produce a sound that New Orleans is now proud to call its own.

Deanna Bogart
While blues music can convey a sense of longing, the musings and sounds of Bogart's latest album evoke an unconventional wisdom. She begins “11th Hour” as a young girl searching for her sound (“Sweet Pea”), then ends it as a grown woman who lets love slip away (“Eleventh Hour Blues”). And with all of the little journeys she embarks in between, Bogart directs the listener through a swirling mix of blues and jazz. See how bandleader – and Maryland native – Bogart blends her newest songs with the rest of her 21-year-old repertoire at the National Gallery of Art's Sculpture Garden.
