Step-by-step explanation:
Led Zeppelin defied the emerging system of rock categories in the late 1960s in several ways:
- Genre-blending: Led Zeppelin incorporated elements of various genres such as blues, folk, and hard rock, creating a unique and distinct sound that didn't fit neatly into existing rock categories.
- Experimental approach: Led Zeppelin pushed the boundaries of rock music through their use of innovative instrumentation, complex song structures, and unconventional recording techniques.
- Lack of singles: Unlike many of their contemporaries who focused on creating hit singles, Led Zeppelin focused on creating cohesive albums, which further defied the categorization of their music.
