“…excellent soloists: soprano Barbara Allen Hill and tenor Thomas Valenti both sang with color, stamina, and control. Hill sounded luminous in “Hail Mary” and “Heaven is here.”

“ “Agnus Dei” (Lamb Of God), is so angelic and powerful from the very first notes and throughout. The female soloist [Barbara Hill] has one of the most beautiful voices you will ever hear.”
