Born December 2 1968, Nate Mendel has been the band's bassist since splitting from his previous band, Sunny Day Real Estate in 1994 and apart from Dave, is the only Foo Fighter to have been there since day one.

Nate has reunited with Sunny Day Real Estate twice for two more albums before the group broke up a second time. He then joined with other former SDRE members Jeremy Enigk and William Goldsmith(a former Foo Fighter himself) to form The Fire Theft, who released a self-titled album in 2003.

Nate is known by cult Foo fans for his trademark head bopping and shuffle when playing live. This is more commonly known as the "Nate bop". Some fans even believe that he enters into some sort of trance and goes into his own world during gigs, thus why his bass riffs always hit the spot.
