The Costa Rica News (TCRN) – Carnival revelers are packing streets across Brazil for raucous open-air parties that begin at daybreak and pulse through the night.

But attention is now turning to the sequin-drenched samba group parades set to begin in Rio de Janeiro.

The nightlong parades will have six samba groups showing off both Sunday and tonight, with powerful percussion sections, elaborate floats and more than 2,500 participants in each parade, which last about an hour.

Millions of Brazilians watch the parades live on TV and root for their favorite samba groups with a passion rivaled only by the allegiances held to football teams.

Forty judges take part and the groups are judged in 10 categories, from the quality of the drumming to the extravagance of the costumes.
