Question about Ayumi Hamasaki?!

[Crissy Snow]

Well I was reading her biography and it says she went to New York to take vocal lessons in Manhattan. I am wondering if that teacher who taught her was Wendy Parr a Speech Level 4 teacher who was taught under Seth Riggs. Basically Seth Riggs is the master teacher of vocal lessons and stars/grammy winners go to him for guidance and lessons.

But anywho does anybody know the name of the vocal teacher that taught Ayumi Hamasaki? I am just curious to know. I am assuming it was Wendy Parr.
