I know literally nothing about the composer Charles Piroye, but Wikipedia offers the following:
Very little is known about his life, and even the dates of his birth and death have not yet been determined. He may have been born in Paris. His teachers were Jean-Baptiste Lully and Michel Lambert, but some of the surviving music suggests not their influence, but that of Marc-Antoine Charpentier. From 1690 to 1712 Piroye was organist of the Jacobins Church at Rue St. Jacques, and from 1708 to 1712 organist at Saint-Honoré. He started publishing his music at least as early as 1695; a tax register from that year lists him among the organists of the second rank (the "first rank" included François Couperin, Louis Marchand, and others). By 1712 he was evidently very well known, for the publisher of Piroye's Pièces choisies mentioned the composer's exceptionally high reputation ("each day renewed applause") in the preface. Évrard Titon du Tillet, writing in 1732, referred to Piroye as one of the "most able organists recently deceased", providing the only clue as to when the composer died.
Piroye's organ works from Pièces choisies (Paris, 1712) cover much more ground than the French organ school tradition of the period. Most of his works are not fugues, hymn settings, trios, etc., but dialogues between different choirs of the organ. They all have descriptive titles: La Béatitude, La Paix, L'Allégresse, L'Immortelle, La Brillante, La Royal. Other works by Piroye also show a distinct, individual style.
