In June 2010, Eric Clapton gathered a veritable Who's Who of the world's most talented guitar players at the third Crossroads Guitar Festival, an 11-hour celebration of the six-string that attracted a sold-out crowd of more than 27,000 music fans to Chicago's Toyota Park. All profits from this daylong display of guitar virtuosity benefited The Crossroads Centre in Antigua, a treatment and education facility Clapton founded to help people suffering from chemical dependency.
