The six or seven most recent podcasts are far better than the earlier ones when we were finding our way. Even so, the music as a whole is superior to anything else currently available in its genre. For that reason I would rate the overall podcast with five stars (even though I have serious reservations about the first three shows).
Nothing new has appeared because it is very difficult to get top musicians to perform at no charge and because the free music has resulted in NO album sales. Maybe there's a lesson in that ….
