Live at the Royal Festival Hall is an album by the John McLaughlin Trio, featuring percussionist Trilok Gurtu and bass guitarist Kai Eckhardt. It was recorded at the Royal Festival Hall in London on 27 November 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.
