Craig Sellar Lang (13 May 1891 – 24 Nov 1971) was a New Zealand-born British organist, composer and music teacher. His best-known work is the Tuba Tune for organ.
Here is a nice prelude on the hymn Dominus Regit Me (The Lord's My Shepherd). It is from a series of preludes for manuals only.
Recorded on the standard Hauptwerk settings and being new to be not sure if volume level is OK.
