I don’t listen to too much of the more classic prog stuff, but here are some more modern ones that you might be into:
- Porcupine Tree (Gavin Harrison was the drummer in King Crimson)
- The Pineapple Thief (Another Gavin Harrison band)
- Haken (Recommend starting with The Mountain - my favourite)
- Leprous (Older stuff has more distorted/screamed vocals, newer stuff is a lot cleaner)
- Thank You Scientist
