This morning I was privileged to hear Gustav Holst's (1874-1934) wonderful setting of the Nunc Dimittis in the context of a Candlemas Mass and Procession at S. Clement's in Philadelphia. I had hoped it would be on CPDL (this work may be recent enough to still be copyright), but I suppose I'll just have to buy a piece of music for a change;-)
In any case, I did find a wonderful recording of this work by the Winchester Cathedral Choir under the great conductor David Hill. Have a listen.
