Id like to go along with Tekker and Stratrat too, even though I'm quite a few years further down the line than you are, I still knew nothing about music. The
plane talk book is a really easy read, I've read it 3 times now and picked up something new each time. The DVD shows you how to turn the theory into practice. I genuinely believe it'll be a great benefit to you right from the start.
I see you went ahead and ordered it, I'll be very surprised if you have any regrets.
good luck,
John
