BartK I have been checking multiple times a day. The only info I have comes from the Community tab of his youtube channel, where he says:
I've been under the weather this week, and editing an episode on Chopin's Etudes is almost as hard as playing them. It's a behemoth, coming in 2 parts (with Garrick's segments occupying a full audio episode).
Getting some rest and will post Part 1 this weekend, with videos to follow. Still finalizing the new release schedule for remaining episodes.
Your patience will pay off!
