I'm very fortunate to have been introduced to Open Studio by the best Jazz musicians I know here in Prague. I used to be only a singer and a mediocre guitar player. Thanks to Peter Sprague's course, I can now play Jazz standards with some really cool musicians who noticed the improvement. The podcasts are incredibly awesome! The only negative thing I can say is that it is kinda addictive. :-) I don't go for an all-access pass because I get distracted too easily by all the great stuff there. Thank you Open Studio team for bringing all this great stuff to us!
