Grunge

A genre of music that started in the mid-80s. Although it only gained mainstream recognition in the early 90s due to the success of grunge band Nirvana. Nirvana was NOT the first grunge band, but without them, you probably wouldn't even know what grunge is. Grunge is characterized by its big, loud guitar riffs and rough, lazy vocals.

Here's some examples of grunge bands:
Alice In Chains

Mudhoney
Melvins

Nirvana

Pearl Jam
Sound garden

Grunge is NOT a theme used on Tumblr to describe artsy pictures of edits of Melanie Martinez.

Poser- "well I listen to pop-punk, have a nirvana t-shirt from hot topic and describe things as grunge on Tumblr. So I'm definantly grunge."
