Pearl Jam is an American rock band formed in Seattle, Washington, in 1990. Compared with the other grunge bands of the early 1990s, their style is noticeably less heavy and harks back to the classic rock music of the 1970s. Pearl Jam has cited many punk rock and classic rock bands as influences, including The Who, Led Zeppelin, Neil Young, Kiss and the Ramones. Pearl Jam’s success has been attributed to its sound, which fuses "the riff-heavy stadium rock of the '70s with the grit and anger of '80s post-punk, without ever neglecting hooks and choruses.
Since its inception, the band's line-up has comprised Eddie Vedder (lead vocals), Mike McCready (lead guitar), Stone Gossard (rhythm guitar) and Jeff Ament (bass). The band's fifth member is drummer Matt Cameron (also of Soundgarden), who has been with the band since 1998. Boom Gaspar (piano) has also been a session/touring member with the band since 2002. Drummers Dave Krusen, Matt Chamberlain, Dave Abbruzzese and Jack Irons are former members of the band.
To date, the band has sold nearly 32 million records in the United States and an estimated 60 million worldwide. Pearl Jam has outlasted and outsold many of its contemporaries from the alternative rock breakthrough of the early 1990s, and is considered one of the most influential bands of that decade. Stephen Thomas Erlewine of AllMusic referred to Pearl Jam as "the most popular American rock & roll band of the '90s"
