Ray Steadman-Allen was for many years the driving force in Salvation Army music. His publication list of both brass and vocal works can be measured literally by the hundred. 'The Lord is King' is arguably his crowning achievement of over twenty major works for brass band. Although described as a suite, the work is more symphonic in conception and scale as well as being formidable to perform. The work is based on the Welsh hymn tune 'Llangollen' to which the hymn 'The Lord is King, I own His power' are associated. The three movements derive inspiration from the lines 'My joy, my toil, my craftman's skill, all have their place, and serve His will' found in verse five of the hymn.
