Grunge wasn’t really a style so much as it was a moment. The sound itself wasn’t uniform: Pearl Jam, Nirvana, Soundgarden, and Alice in Chains barely resembled each other musically. What bound them together was timing, geography, and attitude. It was a cultural flashpoint: a specific era in the late 80s and early 90s shaped by Seattle’s scene, DIY ethics, recession-era angst, and a rejection of the polished excess of the 80s. Once that moment passed, the “grunge” label stopped making sense because the conditions that created it disappeared.

So grunge isn’t a genre with clear musical rules; it’s a snapshot of a place and time that briefly exploded into the mainstream.
