Musical pentagon.

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.
