"Open Studio, as far as I'm concerned, is in the happiness business. I can't think of any other service that makes me as happy as Open Studio, and especially the Jazz Piano Method, the You'll Hear It podcast, and Adam Maness's Facebook instruction. The courses are all world-class, the production values are superb, the customer service is personable and efficient, the community is supportive. If Open Studio didn't exist, I'd be a much less happy person. It's been life-changing."
