Guitar legend John McLaughlin performed across America during Summer 2013 with his trailblazing band, the 4th Dimension (Gary Husband on keyboards and drums, Etienne Mbappe on bass, Ranjit Barot on drums). The final concert in Boston, which was held at the Berklee College of Music, was recorded for this live release. This fiery performance features music from John's recent studio albums Now Here This and To the One, not to mention the classical Mahavishnu Orchestra song. "You Know, You Know".
