Randall Padilla who teaches at Langlois is the best. No other instructor that I have met or heard of can play as well as he plays or is as knowledgeable as he is (GIT).
I take lessons from him privately and have been playing for over 34 years. I can tell you that I learned more about music in the first 3 lessons than I have the entire time I have played.
I took lessons from Gottschalks but was receiving no material to work on during the week and was learning nothing about music and why it works.
Padilla's lessons are 5 star, don't waste your time/money anywhere else.
