"Green River" was an influential Seattle band in the 1980s, lasting only four years and named after a (then at large) serial killer in Washington. They were one of the first grunge bands.
Green River arguably had little impact outside Seattle, though they did form a friendly alliance with emerging American indie rock bands, most notably Sonic Youth who would later quote the Green River song "Come On Down" in their 2000 song "Nevermind (What Was it Anyway?)". However, the impact Green River had on the music made in Seattle would eventually be felt around the world. Their influence could be felt on both their contemporaries (Soundgarden, The Melvins) (though influence on the part of the Melvins was a two way street) and later Seattle bands (Nirvana, Alice in Chains). Before Nirvana, or indeed Mudhoney, Green River was the flagship band at legendary Seattle label Sub Pop, and through the bands who would form when the band split up (Mother Love Bone, Pearl Jam, Mudhoney) the members went on to influence millions of people world wide.
