As a seasoned player of intellectual games, having played a lot of them, I suggest you play one too. I'll name a musical group, a fairly well-known one, and give you one clue. You write your guesses to me in a private message. If, after a certain period of time, there are no correct answers, I'll give a second, easier clue, and again you write your answers to me in a PM. Accordingly, for an answer after 1 clue - 5 points, after the 2nd - 4, and so on. The next person to name a group is the one who guessed the answer to the previous riddle. Let's go.

Clue #1. The title of one of this group's albums is related to a nuclear submarine.

The Beatles-"Yellow submarine".

And here's another incorrect answer. First, "yellow submarine" is not the name of the submarine, but merely an epithet describing it; second, I highly doubt it's a nuclear submarine. (I will definitely check this, but the first point is enough to consider the answer incorrect.)

Hint #2: Throughout the group's history, 18 musicians have been members.

It's a shame that the topic died out:(

I don't have any versions, except for the band Nautilus Pompilius and the nuclear submarine USS Nautilus (SSN-571), but that's the name of the band, not an album.

Maybe someone will try to guess something easier?

I agree, that’s a shame. Maybe Wolf will take care of it?

I wish there was a hint... because besides U-2, nothing else comes to mind.
