Dave Grohl is not the only one from the band that has an impressive C.V. Two members of the band, Nate Mendel and William Goldsmith, were formerly of Sunny Day Real Estate who would later form The Fire Theft, a 90s rock band. One of their guitarists played with Me First and the Gimme Gimmes, a pop punk band. Pat Smear ofter toured with Nirvana and had been part of the first hardcore punk Grohl had been in, Scream. And the drummer for Foo Fighters, Taylor Hawkins, once toured with Alanis Morissette.
What is surprising about Foo Fighters is how they were and were not influenced by Nirvana. They sound nothing like Nirvana, since Foo Fighters do not have any of the punk, metal or grunge sound that Nirvana was so infamous for. Foo Fighters famously has connections to Led Zepplin, Queens of the Stone Age, and Queen, and they are much more similar in sound to these bands than Nirvana. However, many of the songs sound lyrically, like they could be love letters to Cobain, who Grohl had a close relationship with, even though Grohl only claims that "Friend of a Friend" is about Cobain. In addition to being in a band, they were roommates and dated, at the same time, two of the members of Bikini Kill, Kathleen Hanna and Tobi Vail.
The band also has a wonderful sense of humor, seen in videos like "Everlong" and "Learn to Fly." These videos often combine Saturday Night Live-like sketches with their music.
I am so happy to read that Novoselic will be part of Foo Fighters. Grohl choose not to have Novoselic as part of the band originally because it would have encouraged people to view Foo Fighters as "Nirvana without Cobain," even though the band's sound is far more arena rock and less punk than Nirvana ever was.
