Question: In what year was the band that sings the song "Before I Forget" founded?

<P0-S0> "The Entertainer" is a single by singer Billy Joel released as the only single from his 1974 album "Streetlife Serenade". <P0-S1>  The song peaked at #34 on the US charts, a Top 40 hit for Joel that year. <P0-S2>  The song is a cynical and somewhat satirical look at the fleeting fame of a musician and fickle public tastes ("Today I am your champion / I may have won your hearts / But I know the game / You'll forget my name / And I won't be here / in another year / if I don't stay on the charts"); this theme would be examined in the later song "It's Still Rock and Roll to Me". <P0-S3>  Another verse in the song references the shortening of Joel's song, "Piano Man", from 5 minutes and 38 seconds to 3 minutes and 5 seconds to fit a radio slot, referenced by the lyrics "It was a beautiful song, / but it ran too long / If you're gonna have a hit, you gotta make it fit / So they cut it down to 3:05." <P0-S4>  Additionally, the timing printed on the label of the 7" release of "The Entertainer" was 3:05, although the actual 45 length was 3:11 (while the album length was 3:41). <P0-S5>  In the single version, Verse 3 (which starts at 1:02 in the album version) is edited out, and Verse 2 (which starts at 0:40) contains a steel guitar in its second half, which is actually featured in the second half of the "third" verse in the album version; indeed, on the single mix, the instrumental crescendo of the album version is anticipated by bringing the fuller instrumentation of Verse 3 under the vocals of Verse 2. <P0-S6>  As a result of this, the slightly emptier original instrumentation of Verse 2 (which includes a downward slide on the synth) and the vocals of Verse 3 are completely omitted, while the instrumentation of Verse 3 (featuring the steel guitar) does appear, but earlier. <SEP> <P1-S0> "Before I Forget" is a Grammy Award-winning song written and recorded by American metal band Slipknot. <P1-S1>  It is the third single from their 2004 album "". <P1-S2>  It was listed as AOL's top metal song of the decade. <SEP> <P2-S0> Slipknot is an American heavy metal band from Des Moines, Iowa. <P2-S1>  The band was founded in September 1995 by percussionist Shawn Crahan and drummer Joey Jordison. <P2-S2>  After several lineup changes in its early years, the band settled on nine members for more than a decade: Corey Taylor, Mick Thomson, Jim Root, Paul Gray, Craig Jones, Sid Wilson, Shawn Crahan, Chris Fehn and Joey Jordison. <P2-S3>  Gray died on May 24, 2010, and was replaced from 2011–2014 by former guitarist Donnie Steele. <P2-S4>  Jordison left the band on December 12, 2013. <P2-S5>  Steele left during the recording sessions for "". <P2-S6>  The band found replacements in Alessandro Venturella on bass and Jay Weinberg on drums. <P2-S7>  After the departure of Jordison, as of December 2015 the only founding member in the current lineup is percussionist Crahan; the other remaining members of Slipknot have been members since the release of the band's 1999 eponymous debut album. <SEP> <P3-S0> The discography of Scottish rock band The Twilight Sad consists of four studio albums, four compilation albums, eleven singles, and five extended plays (EPs). <P3-S1>  The band currently consists of James Graham (vocals), Andy MacFarlane (guitar, producer), and Mark Devine (drums). <P3-S2>  The Kilsyth-based band formed in 2003 and were signed to Fat Cat Records when Alex Knight, co-founder of the label, went to Glasgow to watch the band perform their third gig and signed them on the spot. <P3-S3>  The band released their debut EP "The Twilight Sad" in November 2006 in the United States only, followed by their debut album "Fourteen Autumns & Fifteen Winters" in April 2007, which garnered widespread critical acclaim. <P3-S4>  The album spawned two singles, "That Summer, at Home I Had Become the Invisible Boy" in April, and "And She Would Darken the Memory" in July. <P3-S5>  The following year, the band released "Here, It Never Snowed. <P3-S6>  Afterwards It Did", a mini-album of reworked versions of songs from "Fourteen Autumns & Fifteen Winters" and two non-album tracks, inspired by stripped-down live performances. <P3-S7>  A collection of live versions and previously unreleased tracks entitled "Killed My Parents and Hit the Road" was released in December 2008. <P3-S8>  The Twilight Sad's second studio album, "Forget the Night Ahead", was released in September 2009 to further acclaim and marked a shift in the band's direction towards a darker and more streamlined sound. <P3-S9>  The album produced three singles: "I Became a Prostitute" in August 2009, "Seven Years of Letters" in October 2009, and "The Room" in April 2010. <P3-S10>  Founding bassist Craig Orzel left the band in February 2010, and the band released "The Wrong Car" EP in September of that year.
