Another group that I found which plays in clubs and other venues where people are dancing is Slavic Soul Party! This brass band from New York describes their style as "BalkanSoul GypsyFunk." On the Slavic Soul Party! website, a quote from the New York Times describes them:
"Fiery Balkan brass, throbbing funk grooves, Gypsy accordion wizardry, and virtuoso jazz chops: Slavic Soul Party! is just what it says. These nine musicians have created an acoustic mash-up of Balkan and Gypsy sounds with North American music, weaving the gospel, funk, dub, jazz, and Latin influences of New York's neighborhoods seamlessly into a Balkan brass setting and always "delivering a great time.""
Slavic Soul Party! has given exciting performances around the world at festivals, clubs, and even a pool at the Russian Baths. Every Tuesday, the band performs at Barbes in Brooklyn. In addition, they have made 5 cds.
Here is a video of a live performance complete with a dancing audience.
WNYC, the public radio station in New York City, interviewed the group and listened to a live performance. Here is a link to the interview:
