Tonight you can party like you’re at a Southeastern European wedding. Brooklyn-based group Tipsy Oxcart is performing at Tropicalia on U Street at 8 p.m. The band blends Balkan music with funk, rock and jazz. You can hear violin solos, get carried away by the clarinet and dance until strangers on the sidewalk distance themselves from your sweaty self. Or you can quietly sip a beverage. Hey, it’s your evening.
