Captured across two nights at Madison Square Garden, the Crossroads Guitar Festival offers a variety of legendary guitarists performing a mix of sultry blues, classic rock and country jams. While Madison Square Garden is an epic arena, the concert remains intimate as Clapton and others collaborate on a sampling of the greatest hits of their careers. Held to benefit Crossroads Centre, a drug treatment and education facility in Antigua founded by Clapton, each concert has become a jam session of Claptonâs closest friends and musicâs biggest stars â where anything can unfold onstage. In fact, this yearâs concert welcomed an impromptu visit from Keith Richards. A full list of participating artists can be found above. In addition to legendary guitar performances, cinema audiences will be treated to exclusive behind-the-scenes footage from this yearâs Crossroads Guitar Festival.
