The Crystals were a trailblazing American girl group of the early 1960s, known for their powerful harmonies and classic pop hits produced by Phil Spector. Their songs—like “He’s a Rebel,” “Da Doo Ron Ron,” and “Then He Kissed Me”—helped define the "Wall of Sound" era, combining catchy melodies with lush, dramatic arrangements. The Crystals’ music captured the excitement and innocence of teenage love, making them stars of the pre-Beatles pop era. Fun fact: Their song “He Hit Me (It Felt Like a Kiss)” was so controversial at the time that some radio stations refused to play it, but it’s now considered a haunting commentary on its subject matter.
