Garage rock
New subgenres that were derived from punk and important in the 1980s included new wave, hardcore punk, post-punk, thrash, and alternative rock. In the 1990s, alternative rock broke through into the mainstream with grunge, and other significant subgenres included indie rock and nu metal. In the 2000s genres that emerged into the mainstream included emo, metalcore and there was a Garage rock/post-punk revival.
