Laura Monks, president of Decca Classics, said the team had been “thrilled” to work with “such a legend”.
“There has been a complete energy in the office, everyone buzzing with excitement because we are helping him deliver on a life long dream”, she told Radio Wales Drive.
Monks, who witnessed Hopkins recording the albumm said the team had goosebumps on their arms and his “life long knowledge” of classical music was clear to those in the room.
“He was listening to the music intently, he was giving notes, it was just really a special and unique thing to see,” she said.
Sir Anthony continues to pay tribute to Wales on another of the album’s tracks, My Fatherland.
He said he wrote the piece to “honour my humble beginnings”, adding “I am the son of my father, the baker”.
Other compositions on the album draw on memories of Port Talbot, childhood visits with his grandfather, the cinema that first caught his imagination, and the people closest to him.
Sir Anthony’s portrayal of cannibalistic killer Hannibal Lecter in The Silence Of The Lambs won him the leading actor gong at the 1992 Oscars.
He went on to star in The Silence Of The Lambs sequel Hannibal (2001) and its prequel Red Dragon (2002).
The actor won a second Oscar in 2020 for his role in Florian Zeller’s The Father which also starred Olivia Colman.
