Topic: Troy Stetina guitar series
If you have hard rock/ metal students Troys books are a great resource to use. I use his method books as a general curriculum and expand from there using my own material or creating additional exercises to reinforce what is taught it the books.
Another good one for kids or adults wanting to learn how to read music is You're in the Band by Dave Clo. It comes with real band backing tracks to play along with.
