In general, instructors put up what they know and think is important. Occassionally, we will concentrate on a particular thing (all the beginners stuff was a concentrated effort).
We are always trying to even it out and find more different stuff. We know we need more jazz, classical and inspired by styles. We will do our best to build out those sections. Also, metal needs some new instructors, and we are working on getting them.
So, over time you will see more. But...we can't promise to do something specific per your request. So, depending on what you were looking for, you might need to hire a local teacher to teach you, or you might find what you need here, or you might like to do both.
Hope that helps.
