I am a strong believer in learning from the best. I believe sometimes its even a good idea to avoid taking advice from high intermediate/ low advanced players because even they can teach you technique that you will later have to unlearn so you can learn superior technique. Breaking habits can be hard and very time consuming.

However I also believe there is more to it than that, you can find incredible players that make lousy teachers. Some even put together a whole bunch of exercises without much thought or benefit to the user as there name alone will sell the dvd etc. Therefore following the statement that "the proof is in the pudding", i think a great way to decide if a learning resource is worth it or not is to look at those that have studied it.

Speed kills, speed kills 2, speed kills 3 and star licks by michael angelo batio fit into the category of learning material i am searching for. They were written by one of the greatest virtuoso's of all time and studied by: dimebag darrel, john petrucci, michael romeo of symphony x, and one of the dragonforce guitarists (can't remember which one).

The purpose of this thread is to find similar learning resources, who was it written by, and who has studied it?

thanks in advance for any recommendations
