Hi Jerry,

If you look down the left side of the home page you'll find some options: style lessons (rock), technique lessons and artist studies.

We also have a new directory system where you can browse all lessons by an instructor, this is a new feature on every instructor's home page.

Here's an easy place to find which instructors have rock lessons:

Hope this helps!
