This makes the quotation be "A MODERN DAY NAMESAKE OF THE FIRST INDEPENDENT COUNSEL TO SERVE UNDER TWO VICE PRESIDENTS SINGS COUNTERTENOR IN THIS KIND OF EARLY ENGLISH VOCAL MUSIC ENSEMBLE."

The acrostic in the answers spells NO VICE STARTING WORDS.

George Clinton in the early 1800s was the first vice president to serve under two presidents, and his modern day namesake musician George Clinton is best known for FUNK music.
