The developing genre came to be known as "grunge", a term meaning "dirt" or "filth". The term was perhaps seen as appropriate due to the dirty sound of the music and the unkempt appearance of most musicians. Grunge fused elements of hardcore punk and heavy metal into a single sound, and made heavy use of guitar distortion, fuzz and feedback. The lyrics were typically apathetic and angst-filled, and often concerned themes such as social alienation and entrapment, although it was also known for its dark humor and parodies of commercial rock.
Bands such as Green River, Soundgarden, the Pixies, the Melvins and Skin Yard pioneered the genre, with Mudhoney becoming the most successful by the end of the decade. However grunge remained largely a local phenomenon until 1991, when Nirvana's album Nevermind broke into the mainstream. Pearl Jam also contributed to this with their album Ten. Both bands were more melodic than their predecessors and were instant sensations worldwide, but they refused to buy in to corporate promotion and marketing mechanisms. During 1991 and 1992, other grunge bands such as Soundgarden, Alice in Chains and Candlebox gained a wider audience. Commercial rock and metal faded almost completely from the mainstream.
While grunge itself can be seen as somewhat limited in range, its influence was felt across many geographic and musical boundaries; many artists who were similarly disaffected with commercial rock music suddenly found record companies and audiences willing to listen, and dozens of disparate acts positioned themselves as alternatives to mainstream music; thus alternative rock emerged from the underground. This helped pave the way for bands such as the Smashing Pumpkins and Stone Temple Pilots who were initially stereotyped as grunge but later enjoyed commercial and critical success independent of the genre.
In early April 1994, grunge took a sudden shift in popularity with the death of Nirvana's frontman Kurt Cobain. The death of Alice in Chain's frontman Layne Staley in 2002 contributed to the final demise of the grunge genre[citation needed]. Although grunge bands continued to release albums, the genre began to decline in popularity and, by the end of the decade, many grunge bands had split up, stopped
While the American mainstream was focused on grunge, post-grunge, and hip hop, numerous British groups launched a 1960s revival in the mid-90s, often called Britpop, with bands such as Suede, Oasis, Supergrass, The Verve, Radiohead, Pulp and Blur among the front-runners. These bands drew on myriad styles from the 80s British rock underground, including twee pop, shoegazing and space rock as well as traditional British guitar influences like the Beatles and glam rock. For a time, the Oasis-Blur rivalry was similar to the Beatles-Rolling Stones rivalry, or the Nirvana-Pearl Jam rivalry in America. While bands like Blur tended to follow on from the Small Faces and The Kinks, Oasis mixed the attitude of the Rolling Stones with the melody of the Beatles. The Verve and Radiohead took inspiration from performers like Elvis Costello, Pink Floyd and R.E.M. with their progressive rock music, manifested in Radiohead's most heralded album, OK Computer. Many of these bands became very successful (although Britpop's popularity in America was short, with the exception of Oasis), and for a time Oasis was given the title "the biggest band in the world" thanks to an album selling some 19 million copies worldwide, but the movement slowed down after numerous band breakups, publicity disasters in the United States and slightly less popular support. The Verve disbanded after on-going turmoil in the band between singer Richard Ashcroft and guitarist Nick McCabe. Radiohead has since gone in a more experimental, less radio-friendly direction, beginning with their critically well-received album Kid A. As a consequence
