Post-grunge is a subgenre of alternative rock and hard rock that emerged in the mid-1990s as a derivative of grunge, using the sounds and aesthetic of grunge, but with a more commercially accessible tone. This made post-grunge bands such as the Foo Fighters, Nickelback, Bush, Creed, and Matchbox Twenty among the most commercially successful rock acts of the late 1990s and early 2000s.
Post-grunge bands emulated the attitudes and music of grunge, particularly its thick, distorted guitars, but with a more radio-friendly commercially oriented sound. Unlike early grunge bands, they often worked through the major labels and came to incorporate diverse influences including jangle pop, pop punk, ska revival, and slightly different interpretations of alternative metal and hard rock. The term post-grunge was meant to be pejorative, suggesting that they were simply musically derivative, or a cynical response to an "authentic" rock movement.
Even at the height of their popularity, after the release of Nevermind (1991) brought grunge to international attention, Nirvana experienced increasing problems, partly caused by Kurt Cobain's drug addiction and growing dissatisfaction with commercial success. In late 1992 Cobain was photographed in a T-shirt with 'Grunge is Dead' printed on the front and the genre's decline started to be widely discussed. The death of Cobain in April 1994, as well as touring problems for Pearl Jam, marked a decline for grunge that year. Problems of addiction for Layne Staley of Alice in Chains led to the cancellation of scheduled dates for the band in 1995. As these pioneering grunge bands faltered, major record labels began signing and promoting bands that were emulating the genre. The term post-grunge was coined to describe these bands.
With their more commercially friendly sound, post-grunge bands were among the biggest selling rock artists of the later 1990s and early 2000s in the US, gaining considerable airplay and able to compete with alternative metal and rap rock bands. Partly because of their more mainstream sound and greater commercial success post-grunge bands were criticised by some fans and in the music press for their artistic limitations and lack of authenticity in comparison with original grunge bands.
