Mendel was born and raised in
Richland, a mid-sized city in southeast
Washington. His first instrument was the
violin. At the age of 13, Mendel started to get interested in rock music and joined a band, Mendel stated that "as I picked up that bass I went on a 20-year detour into
punk", helped by his town usually having concerts of
DIY punk bands such as
Scream. This led to a "pretty limited musical education", as despite taking some lessons with a bassist from a local band, Mendel mostly taught himself to play, and "it was all hardcore punk rock, like
Minor Threat,
Black Flag and
Bad Brains. Instead of studying the bass playing of someone like
John Entwistle, which would have given me a foundation of how to play. I just wanted to play a lot of notes fast." Mendel began his musical career in the
hardcore band Diddly Squat, which only recorded a
7" single but did a national tour during the 1988 summer vacation. After Diddly Squat ended, Mendel moved to
Seattle, where he spent four months on the
straight edge band Brotherhood. Afterward, he joined the band Christ on a Crutch, which included bandmate Glen Essary and lasted until 1993. In 1992, Mendel and his
University of Washington housemate
Dan Hoerner decided to form a band, and invited drummer
William Goldsmith to form the group that would end up being named
Sunny Day Real Estate (SDRE). Mendel added that SDRE was an attempt to "play more intricate, interesting music". Just before Sunny Day Real Estate disbanded in 1995, Mendel and Goldsmith were invited by
Dave Grohl to join his band, the
Foo Fighters, during the week of Halloween in late October 1994. He has remained a bandmember ever since, being one of the only original members in the Foo Fighters' current lineup along with Grohl and former
Nirvana live guitarist
Pat Smear. Although Sunny Day Real Estate reunited for two more albums (
How It Feels to Be Something On and
The Rising Tide), he stayed with the Foo Fighters, in Sunny Day Real Estate, he was replaced by Jeff Palmer, and Palmer was replaced by Joe Skyward, when Skyward left the band,
Jeremy Enigk (lead vocalist, rhythm guitarist, and keyboardist) moved to the bass. After Sunny Day Real Estate disbanded once more, he joined with other Sunny Day Real Estate members Jeremy Enigk and
William Goldsmith to form
The Fire Theft, who released a self-titled album in 2003. The band toured in 2009, confirming a new album in the works. However, recording sessions proved to be unproductive and by 2013, the group had broken up once again. == Technique ==
