That's a well-done set.
Overall, preliminary assumption is that this is just an outlet for Dizzy to collab with people in an "official" capacity plus an opportunity for a behind-the-scenes look into Phase proceedings(did someone say "transparency"?). Judging by yesterday's tweet about "not starting another convoluted project right after finishing her last one", this thing is her idea, rather than management's, as to why it's on official channel - i...have no idea.
