"Although I have taken private lessons, I feel that this cd course truly compliments my lessons. Aaron Anastasi's course is like having your own personal coach wherever you go. Every time before a performance, I warm up with Superior Singing Method. I have every cd on my iPod and listen to it while traveling to my next show or back stage before a gig. It's been such an exceptional vocal aide and I am very glad I took the chance on this set.
