massive attack i believe, has a track that has a "hidden track" which is just like 8 minutes of ambient noise. After an immediate banger as well, so it just gaslights you. It's great.

i've always been intrigued by bands and artists that meld songs between the album, it's an interesting experience. Boards of canada does it somewhat. It's pretty hard to distinguish which makes it really interesting to listen to. It's all one thing, but a collection of many different things also. Very interesting.
