Rancid (2000 album): Rancid (also known as Rancid 5 or Rancid 2000) is the eponymously titled fifth studio album by the American punk rock band Rancid.  It is the second eponymous album and was released on August 1, 2000, through frontman Tim Armstrong's label, Hellcat Records.  It was the band's first album released through Hellcat.  It is Rancid's most hardcore offering to date, which was released as a follow-up to the more ska and reggae oriented "Life Won't Wait".  It spans 22 tracks in under 40 minutes, resulting in over 3/4 of the songs clocking at under 2 minutes.  The Japanese version includes one bonus track, "Sick Sick World".  Songs on the album make reference to famous gangster Al Capone, as well as Norse God Loki, John Brown, Ulysses S. Grant, Nelson Mandela, Charles Van Doren, Geoffrey Chaucer's "Canterbury Tales" and Don Giovanni.  Brett Gurewitz (Bad Religion) reunited with Rancid and became their producer for this album.  It was 6 years since he co-produced the band's second album "Let's Go" (1994), although he engineered the band's third album, "...And Out Come the Wolves" (1995).  Rancid and Gurewitz would continue their collaboration for their next three albums, "Indestructible", "Let the Dominoes Fall" and "Honor Is All We Know".

Tim Timebomb: Tim Timebomb is a music project by Tim Armstrong, best known as a member of the punk rock band Rancid.  Armstrong has recorded a large number of songs – a mixture of cover versions, including Rancid covers, and original songs, including some tracks from his musical film project "RocknNRoll Theater" – with a variety of supporting musicians.

...And Out Come the Wolves: ...And Out Come the Wolves is the third studio album by the American punk rock band Rancid.  It was released on August 22, 1995, through Epitaph Records.  Rancid's popularity and catchy songs made them the subject of a major label bidding war (hence the title, "...And Out Come the Wolves" taken from a poem in Jim Carroll's The Basketball Diaries) that ended with the band staying on Epitaph.  With a sound heavily influenced by ska, which called to mind Tim Armstrong and Matt Freeman's past in Operation Ivy, Rancid became one of the few bands of the mid-to late-1990s boom in punk rock to retain much of its original fanbase.  In terms of record sales and certifications, "…And Out Come the Wolves" is a popular album in the United States.  It produced three hit singles: "Roots Radicals", "Time Bomb" and "Ruby Soho", that earned Rancid its heaviest airplay on MTV and radio stations to date.  All the singles charted on Modern Rock Tracks. " …And Out Come the Wolves" was certified gold by the RIAA on January 22, 1996.  It was certified platinum on September 23, 2004.

Honor Is All We Know: ...Honor Is All We Know is the eighth studio album by the American punk rock band Rancid, released on October 27, 2014.  It is the band's first studio album since "Let the Dominoes Fall" (2009), and their second one to be recorded under its current incarnation (Tim Armstrong, Lars Frederiksen, Matt Freeman and Branden Steineckert).  Work on "...Honor Is All We Know" began in 2011 and it was originally planned for a 2012 release, but was repeatedly delayed while the band continued touring and writing new material, and its members were busy with their own projects.  After three years of writing and recording, the album was finished in 2014. " ...Honor is all We Know" is Rancid's shortest studio album; at under 33 minutes, it is a-minute-and-a-half shorter than their 1993 self-titled debut album.  This is also the first Rancid album to be released on Epitaph Records since 1998's "Life Won't Wait".

Rancid (band): Rancid is an American punk rock band formed in Berkeley, California in 1991.  Founded by 1980s punk veterans Tim Armstrong and Matt Freeman, who previously played in the highly influential ska punk band Operation Ivy, Rancid is often credited (along with Green Day and The Offspring) for reviving mainstream interest in punk rock in the United States and bringing punk rock into the mainstream during the mid-1990s.  Over their 26 -year career, Rancid remained signed to an independent record label and retained much of its original fan-base, most of which was connected to its underground roots.

Epitaph Records: Epitaph Records is a Hollywood-based independent record label owned by Bad Religion guitarist Brett Gurewitz.  The label was originally "just a logo and a P.O. box" created in the 1980s for the purpose of selling Bad Religion records, but has evolved into a large independent record label.  Gurewitz took the name from a King Crimson song of the same name.  Throughout the 1980s and 1990s most of the bands on Epitaph were punk and pop punk groups, while there are many post-hardcore and bands signed to the label as well.  A large portion of the record label, known as Hellcat Records, is owned by Tim Armstrong, frontman of the punk rock band Rancid.  Several sister-labels also exist, such as ANTI-, Burning Heart Records, Fat Possum Records, Hellcat Records and Heart & Skull Records that have signed other types of bands.  The label has recently been added to the Forza Horizon franchise as a radio station.

Jacoby Shaddix: Jacoby Dakota Shaddix (born July 28, 1976) is an American musician, singer-songwriter, sporadic actor and former television presenter.  He is best known as being the founding member and the continuous lead singer of the California-based rock band Papa Roach since the band's formation in 1993.

Rancid (EP): Rancid is the eponymously titled debut extended play by the American punk rock band Rancid.  It was released in January 1992 through Lookout!  Records, home of Tim Armstrong and Matt Freeman's prior band, Operation Ivy.  It is a recording of the band in its earliest days as a three-piece.  Although the correct title of the extended play is simply "Rancid", it is commonly referred to as "I'm Not the Only One" or "The Bottle" (because of the cover) among Rancid collectors and fans.

Tim Armstrong: Timothy Ross “Tim” Armstrong (born on November 25, 1965) is an American musician, singer, songwriter, producer, and actor.  He is best known as the singer/guitarist for the punk rock band Rancid and hip hop/punk rock supergroup the Transplants.  Prior to forming Rancid, Armstrong was in the influential ska punk band Operation Ivy.  In 1997, along with Brett Gurewitz of the band Bad Religion and owner of Epitaph Records, Armstrong founded Hellcat Records.  In 2012, through his website, Armstrong started releasing music that influenced him, along with stripped-down cover songs of his own work under the name Tim Timebomb.  He has released at least one song per week since late 2012.  Armstrong is also a songwriter for other artists.  Armstrong won a Grammy Award for his work with Jimmy Cliff and Pink and he has also worked with Joe Walsh.

Transplants (band): Transplants are an American punk rock/rap rock supergroup.  They formed in 1999 when Tim Armstrong (of the bands Rancid and Operation Ivy) played his friend and roadie Rob Aston some beats he had made using Pro Tools and asked Aston if he would consider contributing lyrics.  Initially, Armstrong played all the instruments himself but as the project grew, he invited musician friends such as Matt Freeman (Rancid), Lars Frederiksen (Rancid), and Vic Ruggiero (The Slackers) to add to the sound.  Before long, Armstrong and Aston decided to officially form a band, but to make things complete, they wanted a drummer, so Travis Barker from Blink-182 was asked to join in 2002.
