William Byrd-Sanctus (Mass for 4 voices)

Last week a Sanctus by 19th century composer Johannes Brahms; this time we step back a few centuries for a very beautiful but very different Sanctus by William Byrd.  The best way to experience this is live . . . in church . . . at Mass.  If that's not possible, well, take a look at Isaiah 6:3, put on your earphones, close your eyes, and picture the Seraphim . . .
