Nirvana may have been the band that put an entire generation in flannel, and Pearl Jam and Soundgarden both sold a lot more records, but Mudhoney were truly the band that made the '90s grunge rock movement possible. Mudhoney were the first real success story for Sub Pop Records; their music laid the groundwork for the movement that would (briefly) make Seattle, Washington the new capitol of the rock & roll universe. They took the sweat-soaked and beer-fuelled mixture of heavy metal muscle, punk attitude, and garage rock primitivism that would become known as "grunge" to the hipster audience for the first time with early releases like 1988's Superfuzz Bigmuff and 1989's Mudhoney, and those fans would in turn sell it to a mass audience ready for something new.
