This is not a product, it’s a gift, from one one the great backing vocalists of our time. Well worth 10 or 20 times the cost. The various exercises and warm-ups aren’t unique by any means. But Arnold is giving us all the benefit of 30 years of study and professional singing. To have this guy, whom I’ve marveled at as he flawlessly accompanies musical heroes like James Taylor, and Ry Cooder, be right here in my ear giving me tips, keeping the work light and loose with a bit of humor, encouraging me, is a gift beyond description. It makes me WANT to do the vocal work I’ve been needing to do for a long time. BTW, I was alerted to this app by none other than the great Jackson Browne, who credited Arnold’s app for improving his voice and actually teaching him how to sing properly, 40 years into his singing career! JUST GET IT!
