HOSE WHO CLICK on #79075 will find marvelous items. The first is a special “Mode 7” version of the MAGNIFICAT combining versions from Father Guerrero, Father Morales, and Palestrina.

(In the live recording below, the final movement is omitted). Not only that, but rehearsal videos for each individual voice are provided at #79075. On top of all that, two (2) YouTube videos containing a discussion about this marvelous “Guerrero+” composition are linked to.
