How would you really Discribe Prog?
Is Dream Theater really have anything similar to the likes of Pink Floyd and Porcupine Tree? or something like Spock's Beard?
But then why wouldn't Dredg be Prog? Sure they are poppy but so is newer Porcupine Tree...
Not trying to argue, I am actually confused how you would label it.
Dredg aren't prog because they're not prog, that's why.
It has nothing to do with sounding more "poppy" or not, it's to do with the music. I wouldn't necessarily describe Porcupine Tree as prog.
Prog bands are Yes, King Crimson (Although they dislike the label), early Rush, certain Dream Theater. Porcupine Tree and Dredg are just rock bands.
