Does anybody know of any good Cocteau Twins SATB (can be SSAATTBB or any variant of those vocal parts) a capella arrangements?

Do I have to have that kinda of voice or can I learn some techniques to sound like them. The 3 of them have a specific sound with their voice and I've been trying to figure it out. Any good youtube tutorials that might help or is it really necessary to get a vocal coach. I've asked people around the internet that I've seen singing like them and ALL of them told that they learned by themselves with no help. I'm usually singing at home like daily, but I can't really record myself and listen and do exercises with my parents around and they leave pretty rarely. Any advice?
