Have been looking for this and wasn't sure about the content. I'm also interested in the Hans Zimmer one as well...is it worth the purchase to get? Interesting to see he uses software to score all his pieces, but makes sense.
It's amazing. Truly is. He talks about his methods of brainstorming a track. It's so simple yet he makes masterpieces off it.
His masterclass is more general and motivational rather than technical. I would try to find it free online first!
