Mariah To Join Paula, Matchbox 20 For Benefit

Mariah Carey will join Paula Cole and Matchbox 20 at Radio City Music Hall on May 31 at a benefit sponsored by New York's Z-100 Radio.

Some proceeds from the show will go to PAX, an anti-violence group co-founded by Daniel Gross, whose brother Matthew of the band Bush Pilots was critically wounded last year in a shooting atop the Empire State Building. Tickets for the show go on sale Friday.

The day before the Z-100 show, Mariah will play another radio station concert, the annual KISS-FM show at the Great Woods outside of Boston.
