If they ever decide to go back to Williams’ style, one excellent choice would be Kevin Kaska. To my ears, he’s the best Williams clone out there. The score he did for THE ORVILLE episode “Electric Sheep” is terrific. He doesn’t just try to sound like Williams there, he actually pretty much does sound like him. His orchestrations are vibrant and exciting. Granted, in that episode, some tracks are clearly inspired by things like “Battle in the Snow” and “The Adventures of Mutt”, but they’re far from copies.
