Re: Hello, I'm new here :)
Hi, & a huge welcome to the forum. There's a good sized Brit contingent here, even though this is absolutely the biggest & best international drumming forum.
You nailed grade 8 inside 2 years from scratch? Wow! Big achievement right there. Sorry, unable to help on music choices, especially as Pink Floyd is top of your dislike list :( I must admit, on the surface, Floyd stuff isn't exactly challenging in the drumming department, but not so fast m'lady, some of it's actually difficult to nail. Sounds like you're entering the arena of "feel" post dots & classical structure. That, & working with other players is a hill climb much steeper than getting the technical elements down.
I wish you well, & I'm fascinated to hear how you progress in the widening of your repertoire, as there's elements of your background story that resonate with me.
