For those still holding onto the good vibes from this month’s Golden Festival, head to Barbès on Tuesday to nourish your ears with some good ol’ brass tunes. The talented nine from Slavic Soul Party! are due for their weekly stint at the neighborhood hang’s cozy performance room. If you don’t know the first thing about Balkan brass, funk or Gypsy accordion goodness, here’s your opportunity to get schooled by John Carlson and company. A donation of $10 is strongly suggested.
