The Ronettes, featuring lead singer Veronica "Ronnie" Bennett, are best remembered for their hit "Be My Baby," while The Crystals, fronted by various lead singers including Barbara Alston and Dolores "LaLa" Brooks, had hits like "Da Doo Ron Ron" and "Then He Kissed Me". These groups played a significant role in shaping the girl group genre, setting a precedent for vocal harmony, emotional intensity, and dramatic production in pop music. Their music continues to influence contemporary pop and rock artists.
