Authorities say a fight broke out during a show at New York City music venue Webster Hall where one person was bitten and another stabbed.
One person was arrested in the melee Friday evening during the CBGB Festival. The victims are expected to recover.
Hard-core metal bands were on the lineup, as well as other groups. A late-night nightclub event was postponed.
CBGB representatives say in a statement that the disturbance shouldn't overshadow the events, which included free concerts in Times Square and Central Park. Officials are working with law enforcement.
CBGB was once a famed Manhattan rock venue where bands like The Talking Heads performed in the early 1980s. The venue closed in 2006.
