"What a workhorse! He has mastered and also played steel guitar on a few of my songs! His work is impeccable and you will not be disappointed!"
John DeRosa, award-winning Grammy nominated singer/songwriter (DEKO Entertainment), USA
"Some music sounds best mastered for an arena stage, while other music sounds best mastered with the care, detail and integrity of an engineer that understands where that music came from. Andy De Rosa is the latter. His work on my latest album 'Highland Avenue' is spot on. Every hard mile traveled, every tragedy overcome, every triumph properly celebrated... his mastering work perfectly enhanced my music in all of its ragged glory."
