Live At The Royal Festival Hall is an album by the John McLaughlin Trio, featuring Trilok Gurtu and Kai Eckhardt. It was recorded at the Royal Festival Hall in London on November 27, 1989, and was released on the JMT label in 1990. The album reached number 3 in the Billboard Top Contemporary Jazz Albums chart.
McLaughlin makes extensive use on this recording of the Photon guitar synthesiser, a setup whereby transducers mounted on an acoustic guitar are used to control a synthesiser bank via MIDI. This enables McLaughlin to invoke a range of sounds and effects normally the preserve of keyboard players, resulting in a greater variety of moods and textures than might be assumed from the line-up.
