May I first start by saying thank you - I have struggled for years to find a source of blues & rock piano for advanced players (my background is classical). I think the material on the irocku site is absolutely superb, and I have found the transcriptions, lesson & improvisation videos a tremendous help. I recommend your site to friends who are beginners and seasoned players alike as I can't think of anything else to touch it at present, beyond individual tuition. In short, I love irocku (even if I do harbour a mild hatred for the ridiculously talented pianist in many of the lesson videos).
