New York - J&R Music and Computer World, along with Monster, Intel and Sony Music, are co-sponsoring a free concert by Earth, Wind & Fire this afternoon at Manhattan's South Street Seaport.

Other sponsors of the event include Roland and The New York Times.

According to J&R, the concert celebrates the 40^th anniversaries of both the New York A/V specialty retailer and the Grammy Award-winning R&B band.

Monster will also use the occasion to officially launch its Earth, Wind & Fire-inspired Gratitude headphones.

Observed Adam Block, executive VP and general manager at Sony Music/Legacy Recordings, "The music of Earth Wind & Fire remains as vibrant and vital as ever and there isn't a more appropriate way to celebrate that -- and this milestone anniversary they share with New York's own J&R Music World -- than with a show like this."
