Senator Robert Taft Jr. James was described as "a talented political observer who possessed the ability to call every major election with uncanny accuracy".

In that capacity, he managed to play pieces of songs by punk bands like Circle Jerks and Bad Brains over the school intercom before his morning announcements.

During a Toronto stop on their 1987 tour, Grohl played drums for Iggy Pop at a CD release party held at famed club the El Mocambo.

During a 1990 tour stop on the West Coast, Melvins guitarist Buzz Osborne took his friends Kurt Cobain and Krist Novoselic, both then with Nirvana, to see a Scream performance.

Cobain said in a late 1993 interview with MTV that he initially thought the riff was "kind of boneheaded", but was gratified at how the song developed, a process captured in part in a demo on the Nirvana box set With the Lights Out.

[34] Prior to Nirvana's 1994 European tour, the band scheduled session time at Robert Lang Studios in Seattle to work on demos.

"[53] In 2000, the band recruited Queen guitarist Brian May to add some guitar flourish to a cover of Pink Floyd's "Have a Cigar", a song which Foo Fighters previously recorded as a B-side.

After four months in the studio, with the sessions finished, Grohl accepted an invitation to join Queens of the Stone Age and helped them to record their 2002 album Songs for the Deaf.

[59] Grohl and members of Foo Fighters sometimes perform as a cover band "Chevy Metal",[60] as they did in May 2015 at "Conejo Valley Days", a county fair in Thousand Oaks, California.

To avoid having to cancel the band's upcoming North American tour, Grohl designed a large "elevated throne" which would allow him to perform on stage with a broken leg.

[64] On July 31, 2015, Grohl posted a personal reply to Fabio Zaffagnini, Marco Sabiu, and the 1,000 participants of the "Rockin' 1000" project in Cesena, Italy, thanking them for their combined performance of the Foo Fighters' song "Learn to Fly", indicating (in broken Italian), "...

[75] In 1993–94, he played drums in the Backbeat Band, an alternative rock supergroup that also included Greg Dulli of the Afghan Whigs, indie producer Don Fleming, Mike Mills of R.E.M., Thurston Moore of Sonic Youth, and Dave Pirner of Soul Asylum.

[83] Also in 2003, at the 45th Annual Grammy Awards, Grohl performed in an ad hoc supergroup with Bruce Springsteen, Elvis Costello, and Steven Van Zandt in tribute to the recently deceased singer/guitarist Joe Strummer.

[89] In June 2008, Grohl was Paul McCartney's special guest for a concert at the Anfield football stadium in Liverpool, in one of the central events of the English city's year as European Capital of Culture.

Grohl also helped pay tribute to McCartney at the 2010 Kennedy Center Honors along with No Doubt, Norah Jones, Steven Tyler, James Taylor, and Mavis Staples.

[100] Grohl directed a documentary entitled Sound City (2013) which is about the Van Nuys studio of the same name where Nevermind was recorded that shut down its music operations in 2011.

[103] At 12-12-12: The Concert for Sandy Relief, Paul McCartney joined Grohl and the surviving members of Nirvana (Krist Novoselic and touring guitarist Pat Smear) to perform "Cut Me Some Slack", a song later recorded for the Sound City soundtrack.

[109] On November 6, 2013, Grohl played drums at the 2013 Country Music Association Awards, replacing drummer Chris Fryar in the Zac Brown Band.

While Grohl was filming his Sound City documentary, the group asked the fellow native of Northern Virginia to drum on "I Love Lamp".

[112] In September, the all-star covers album by the Alice Cooper-led Hollywood Vampires supergroup was released and features Grohl playing drums on the medley "One/Jump Into the Fire".

[113] That same year, Grohl invited ten-year-old Collier Cash Rule on stage at a Foo Fighters concert in Kansas City, Missouri and gave him his guitar.

[119][120] On March 25, 2022, the self-titled Dream Widow EP was released to digital streaming services featuring eight tracks ranging from thrash, death and extreme metal.

[126] On February 6, 2010, he appeared as a middle-aged punk rock drummer reuniting the group "Crisis of Conformity" (fronted by Fred Armisen) after 25 years in a skit later on in the episode.

[128] In August 2000, Grohl voiced Daniel Dotson, an egotistical art instructor, in Is It Fall Yet?, the first of two film-length installments for MTV's animated series Daria.

[citation needed] In mid-2010, Grohl added his name to the list of contributing rock star voice cameos for Cartoon Network's heavy metal parody/tribute show, Metalocalypse.

[135] Accompanying the release of Sonic Highways, Grohl directed an eight-part documentary miniseries of the same name that chronicles the album's development and recording across eight different American cities.

[citation needed] Grohl's primary recording guitar is an original cherry red Gibson Trini Lopez Standard that he bought in the early 1990s, while still with Nirvana, because he liked the different style of headstock and the diamond-shaped sound holes on what was otherwise an ES-335.

[152] Following the event, Grohl wrote "Ballad of the Beaconsfield Miners", an instrumental piece,[153] which was included on Foo Fighters' 2007 release Echoes, Silence, Patience & Grace, and features Kaki King.

[175] As for producing music, he refuses to use in-ear monitors despite their ability to protect his ears because it "removes [him] from the natural atmosphere sound so [he] cannot hear [his] bandmates".
