Organizers of Byron Bay's annual Bluesfest have pulled off a major coup with the announcement today (Nov. 3) that Bob Dylan, BB King and Elvis Costello will headline the 2011 edition.

The triumvirate are all first-timers at the popular Bluesfest on the northern coast of New South Wales, which director Peter Noble admits is now facing "an embarrassment of riches."

Noble has been chasing Dylan's signature since 2003, when the American folk legend was booked to perform but pulled out at the 11th hour.

Others confirmed to the April 21-25, 2011 line-up include Ben Harper and Relentless7, Michael Franti and Spearhead, Rodrigo y Gabriela, the Cat Empire and the Blind Boys of Alabama featuring Aaron Neville.

Held annually over the Easter long weekend, Bluesfest this year celebrated its 21st anniversary with a move to a new permanent site at the Tyagarah Tea Tree Farm, about 10 minutes drive north of the coastal town.

The purpose-built site played host to more than 80,000 guests, and a bill which included Jack Johnson, Crowded House, Buddy Guy, Gipsy Kings, Roger Hodgson from Supertramp, Orquesta Buena Vista Social Club, the Fray, Angus and Julia Stone, Lyle Lovett and Jeff Back.

In October, the fest was rewarded with the big prize, the Australian Event of the Year gong at the Australian Event Awards.

The Bluesfest started in 1990, pulling a crowd of 6,000 to its four-day indoor event at the Arts Factory in Byron Bay. In the mid-'90s, the festival moved outdoors to Belongil Fields; it later spent a decade at Red Devil Park before heading back to Belongil Fields.
