Problem: Background: Shinedown is an American rock band from Jacksonville, Florida formed by singer Brent Smith in 2001 after the dissolution of his previous band. Smith, still under contract with record label Atlantic Records, recruited the band's original lineup of Jasin Todd as guitarist, Brad Stewart on bass, and Barry Kerch on drums. Consistent for the first two album cycles, a few lineup changes followed in the late 2000s, eventually stabilizing with Smith and Kerch alongside Zach Myers on guitar and Eric Bass on bass. The group has released five studio albums:
Context: Work on a fourth studio album began in February 2011, with the band spending the first half of the year writing and demoing over 33 songs. The band again decided to work with Cavallo as a producer, but moved into a new sound and lyrical direction on the album, capturing a more of a message of "empowerment, perseverance, and inspiration", inspired by Smith's then-recent change of getting sober and living a healthier lifestyle, and the new band members contributing to the writing process for the first time on an album. The recording process wrapped up about a year later in February 2012, and the album, Amaryllis, was released the next month, on March 27, 2012, in 30 countries simultaneously, through a joint release between Atlantic and Roadrunner Records in countries Atlantic did not distribute into. Amaryllis debuted at number four on the Billboard 200 charts, selling 106,000 copies in its opening week. While the opening sales doubled the debut of The Sound of Madness, overall sales fell well short, with the album only being certified Gold, indicating a half million copies sold. Five singles were released from the album: "Bully", "Unity", "Enemies", "I'll Follow You", and "Adrenaline". The band's singles once again fared well, albeit it slightly below The Sound of Madness singles; "Bully" and "Unity" topped the Billboard Mainstream Rock Charts, "Enemies" and "I'll Follow You" peaked at number 2, and "Adrenaline" peaked at number 4. Additionally, only "Bully" managed to have any cross-over success, break into the Billboard Top 100 chart, at number 94. and eventually being certified Gold as well. Shinedown also contributed the non-album song titled "I'm Alive" to the soundtrack of the 2012 film The Avengers. In November 2012, Smith announced in an NME interview that a follow up Shinedown album had already been recorded. Smith stated "We've actually, we have another record of material. It's actually recorded...It's still very massive, it still has an epic feel to it all, but the tempo is a little slower, and the subject matter is a little different. I would say it's actually a bit darker, a little bit more mischievous." Despite the announcement, the band proceeded to move continue on with the Amaryllis touring cycle, touring through 2013 to complete another two year touring cycle. Shinedown and Three Days Grace embarked on a co-headlined tour beginning in February 2013, and went on another iteration of the yearly "Carnival of Madness" tour with Papa Roach in later 2013. In April 2013, Smith and Myers recorded ten acoustic cover songs, selected out of a pool of over 4,000 fan requests, selecting a variety of different types of songs, from Metallica's "Nothing Else Matters" to Adele's "Someone Like You". The tracks were released across two separate EPs, Acoustic Sessions on January 28, 2014, and Acoustic Sessions Pt. 2 on March 28, 2014, with performance videos created for every track on the first EP. The band took much of 2014 off, a rarity for the band, which had pretty consistently moved back and forth between recording and touring for each album cycle. The time off was for the band to rest, specifically Smith, who had damaged his vocal chords and contracted oral thrush from the constant years of touring prior.
Question: why did it take them so long to release the album if they started working on it in 2011?
Answer: the new band members contributing to the writing process for the first time on an album.

Background: Hole was an American alternative rock band formed by singer and guitarist Courtney Love and lead guitarist Eric Erlandson in Los Angeles, California in 1989. Influenced by Los Angeles' punk rock scene, and produced by Kim Gordon of Sonic Youth, the band's debut album, Pretty on the Inside (1991), attracted critical interest from British and American alternative press. Their second album, Live Through This, released 1994 by DGC Records, which featured less aggressive melodies and more restrained lyrical content, was widely acclaimed and reached platinum status within a year of its release. Their third album, Celebrity Skin (1998), which garnered them four Grammy nominations, marked a notable departure from their earlier punk influences, boasting a more commercially viable, "mature" sound.
Context: In the winter of 1998-99, Hole went on tour to promote Celebrity Skin, joining Marilyn Manson, who was promoting his album, Mechanical Animals (1998) on the "Beautiful Monsters Tour". The tour turned into a publicity magnet, and Hole dropped out of the tour nine dates in, due to both the majority of the fans being Manson's, and the 50/50 financial arrangement between the groups, with Hole's production costs being disproportionately less than Manson's. Manson and Love often mocked one another onstage, and Love attacked Manson's stage antics, which included tearing up a Bible during performances: "You know, whenever somebody rips up the Bible in front of 40,000 people, I think it's a big deal," she said during a 1999 interview. Hole officially announced that they would be dropping out of the tour after a poorly received concert at the Rose Garden Arena in Portland, Oregon, which ended with Manson fans booing the band. The band continued to book shows and headline festivals after dropping off Manson's tour, and according to Auf der Maur, it was a "daily event" for Love to invite audience members onstage to sing with her for the last song at nearly every concert performance. On June 18, 1999 during Hole's set at the Hultsfred Festival in Sweden, a 19-year-old girl died after being crushed by the mosh pit behind the mixing board. Hole played its final show at Thunderbird Stadium in Vancouver on July 14, 1999. In October 1999, Auf der Maur quit Hole and went on to become a touring bassist for The Smashing Pumpkins. Samantha Maloney also quit a few months later. The band's final release was a single for the movie Any Given Sunday (1999). "Be a Man", released in March 2000, was an outtake from the Celebrity Skin sessions. Love and Erlandson officially disbanded Hole via a message posted on the band's website in 2002. After the split, the four musicians each took on projects of their own: Erlandson continued to work as a producer and session musician, eventually forming the experimental group RRIICCEE with controversial artist Vincent Gallo. Love began a solo career, releasing her debut, America's Sweetheart, in 2004. Melissa Auf der Maur also embarked on a solo career, and released her self-titled debut album in 2004, which included Erlandson performing lead guitar on the track, "Would If I Could." Her second album, Out of Our Minds, was released in March 2010. Hole's body of work from its inception to its first disbandment includes thirteen singles, three LPs, three EPs, and one compilation album.
Question: why did they disband after this tour?
Answer:
In October 1999, Auf der Maur quit Hole and went on to become a touring bassist for The Smashing Pumpkins.
