I have found the site content, set-up, and the execution have been wonderful and a great value. I am a jazz oriented upright bassist at the intermediate level and I want to become advanced. So far, I have purchased Rhythm Section Fundamentals, the Brazilian Rhythm Section and both Christian McBride bass courses. I love having lifetime access. The software also works great and the available transcriptions are a key learning tool for me. The lessons present many valuable pieces of wisdom with ample demonstrations more than giving tons of exercises, which I love. However, there are now companion videos in Christians course to help with day to day practice and breaking down concepts. The few I have tried so far are excellent and provide a really great recourse to get some serious practice done. Great value overall for the price of a small number of private lessons! In these pandemic times, Open Studio is great way to stay motivated - it has many podcasts and live stream sessions for free that provide a great means of connection community of jazz musicians.
