Which musical movement is characterized by the use of heavy distortion and aggressive sound?

The musical movement known for its heavy distortion and aggressive sound is Heavy Metal. This genre emerged in the late 1960s and early 1970s, characterized by its loud, distorted guitars, emphatic rhythms, and often powerful vocals. Heavy Metal bands typically employ a range of musical techniques, including intricate guitar solos and a prominent use of amplification, contributing to the genre's aggressive sound. The themes in Heavy Metal often explore darker or more intense subjects, aligning with the intense musical backdrop.

Punk Rock, while also aggressive, focuses more on a raw and stripped-down sound with a DIY ethos. Grunge incorporates some aspects of heavy distortion but complements it with a more melancholic tone and influences from alternative rock. Goth Rock emphasizes atmospheric and dark aesthetics, but it doesn’t typically feature the same level of distortion or driving heaviness found in Heavy Metal. Therefore, Heavy Metal is the most accurate choice for the description provided.
