music

Porcupine tree, genesis, yes, rush, opeth, steven wilson, dream theater (start with panic attack), king crimson, pink floyd, tool, frank zappa, Hocus Pocus by focus, The Ocean, Loathe, the pineapple thief, a perfect circle, and my absolute favourites are

Storm corrosion, chroma key. Both of these are calming, haunting, ethereal masterpieces that can be listened on loop forever.

I'm definitely bleeding out of the genre at this point but they all at least have a prog vibe.

Also I don't know if this even counts as prog or what it even counts as but Cardiacs has some good songs.
