Final answer:
The genre that combines elements of punk rock and heavy metal/hard rock is Grunge. It originated in the Seattle area, featuring heavier guitar sounds, slower tempos, and darker lyric themes, with a more casual, everyday fashion sense among its musicians.
Step-by-step explanation:
The genre that draws from both punk rock and heavy metal/hard rock is Grunge. Grunge is a style of rock music that emerged in the late 1980s and early 1990s, particularly in the Seattle area. It incorporates elements from punk and metal, creating a unique sound. Grunge bands often focused on darker subject matter in their lyrics, including political issues, mental illness, and drug addiction, and they favored a less polished image compared to their glam metal counterparts.
Sonically, grunge is characterized by its heavy guitar sound, often with detuned guitars to create a deeper tone, and its slower tempo. The vocal style can also be rawer and more intense. Visually, grunge musicians contrasted greatly from the fashion of other rock genres at the time, opting for a more subdued, everyday look that included flannel shirts and work boots over the flamboyant styles of hair metal.
