Query: One of the greatest!

Joanie Madden is the best selling whistle player of all time.... her albums Song of the Irish Whistle 1 and Song of the Irish Whistle 2 are beautiful heart wrenching and soul moving masterpieces. Whistle on the Wind is Joanie's first solo album and delves into the more fast virtuoso playing. No wonder she won two world champion titles on whistle! It's fantastic!
