'N Sync, Destiny's Child [ tickets ], Wyclef Jean [ tickets ] and Monica [ tickets ] are scheduled to perform during a Dec. 1 benefit concert at New York's Beacon Theater for LIFEbeat, a not-for-profit HIV/AIDS-awareness organization. Event co-presenter Levi's will webcast the sold-out event live on its website.

Besides earmarking income from ticket sales to LIFEbeat, Levi's has agreed to donate $1 to the organization for every person who logs onto the webcast, up to $50,000.

The event is connected to the World AIDS Day 1999 campaign. Billed as ''the only international day of coordinated action against AIDS,'' the goal of the campaign is to open channels of communication and information regarding AIDS.
