Sunday night Brazilian dance party at Black Betty

NIGHTLIFE

Sounds of Brazil

The long-running Sunday night Brazilian dance party at Black Betty gets some competition this weekend, from within its own Moroccan-themed walls. The Carnaval vs. Mardi Gras battle will pit the bossa nova, samba and South American 70s funk of the regular DJs against their Big Easy cajun sounds of their counterparts. Will the loser have to doff their clothes and don some beads? You’re already in the neighborhood; boogie on by and see.
9 p.m., Black Betty, 366 Metropolitan Avenue (Havemeyer Street), Williamsburg, Brooklyn, (718), 599-0243; free.
