Since its inception, Clapton's vision for the Crossroads Guitar Festival has been to create an event where his friends and contemporaries can have fun and jam together for the benefit of a good cause. This year's Festival will feature a full day of musical performances with once-in-a-lifetime guitar collaborations. Known as pioneers in their field, the roster of artists spans old and new, from BB King to John Mayer. The audience can expect unrivaled entertainment, brilliant guitar work, surprise guests and impromptu jams that are the hallmarks of these performers.
The first Crossroads Guitar Festival, in June 2004 at the Cotton Bowl in Dallas, was an unprecedented collection of guitar icons from blues, rock and contemporary music. The sold-out show was chronicled in a 2-disc DVD that has since gone on to become one of the world's top-selling music DVD's, recently achieving the 8x platinum mark in the United States alone.
"The Crossroads Festival is the realization of a dream for me, to gather a group of amazingly talented musicians to perform on one stage," said Clapton. "The Crossroads performers are all musicians I admire and respect."
Additional Festival artists and elements to be announced shortly.
Shouild be an amazing show...
Seriously, the general opinion seems to be (according to postings on here from a previous thread) that Joe's management are aware of Crossroads and that EC's aware of Joe. I suppose the only people that know for sure are the powers that be...but if Joe isn't invited then someone, somewhere needs a bloody good talking to
