I purchased your 8-course intermediate package recently and I started watching them. I am only through 5 videos of them from definitive improv and the mastering accompaniment courses, but I have to say they are so good that I feel obligated to write a positive feedback. 400USD is the most expensive online course I have bought so far, but in my opinion, it is the cheapest I have ever bought given the content is so clearly explained and packaged with tons of practical techniques which can really take me to the next level. I have tried with face to face lesson with teachers, bought a handful of programmes, watched a ton of youtube videos, and your course is one that I have been searching for a long long time. I'm really really glad I bought your course as a new year gift for myself. the best gift ever.
