"Jon Fausty (February 20, 1949 – September 29, 2023) was an American multiple Grammy Award-winning sound and recording engineer best known for his work on some of the most successful Latin albums ever recorded.
Fausty's career spanned over six decades. He designed studios, produced and engineered recordings throughout the United States, Canada, Cuba and Europe - both in studio and live performances.
'…Jon Fausty generally stayed away from special effects and emphasized capturing performances simply, cleanly, and fast, with the high-quality equipment that was by then a given, even in the more modest New York studios. The net result is that many salsa records from the 1970s through the early 1980s have a timeless, classic sound, which has dated little.'
Fausty had thousands of recordings of which 18 have been awarded Grammy Awards. He won Grammys with Chucho Valdez, Celia Cruz, Ruben Blades, Marc Anthony."
