Bill Thorpe is appreciated by choral directors worldwide. His publications always go above and beyond, including biographical and historical text, plus plenty of relevant illustrations, concurrent historical events, and historical perspective to set the stage. All that said, his new edition of ""the perfect anthem"" is derived entirely from the original Mozart manuscript. A rehearsal piano part is constructed from the strings and organ, and instrumental parts are available separately (392-03082A, $15.00). Finally, although the original Latin text is plainly preferred, he also provides a literalEnglish translation. Another complete package from Thorpe Music.
