David Peebles, Si quis diliget me. The Scottish composer Peebles is mainly known for his metrical-psalm settings. ‘Si quis’ is a through-composed motet for four voices. Francis Heagy later added a superfluous fifth voice, which is omitted from this recording. The work is sung very slowly here, as if to make time stand still. The opening words mean ‘If ye love me, keep my commandments’.
