like any serious singer i have committed time to developing my voice. so who else would be more qualified to teach me how to use my instrument than stevie wonders vocal coach. well i couldn't stop gushing about stevie so we called him...

p.s.
If you look on Seth's wall you will see that huge plaque he got for coaching Michael for the making of Thriller. Wiki says that sales for Thriller are estimated to be between 47-108 million copies sold worldwide. Mind boggling genius aligned with the stars on that one.
