Problem: Background: Mudvayne was an American heavy metal band from Peoria, Illinois formed in 1996. They are known for their sonic experimentation, innovative album art, face and body paint, masks and uniforms. The band has sold over six million records worldwide, including nearly three million in the United States. The group consisted of Chad Gray (lead vocals), Greg Tribbett (guitar, vocals), Ryan Martinie (bass guitar) and Matthew McDonough (drums).
Context: In 2010, Mudvayne again paused to allow Gray and Tribbett to tour with Hellyeah, and because of the supergroup's album releases the band would be on hiatus until at least 2014. With Hellyeah, Tribbett has recorded three albums: Stampede, Band of Brothers, and Blood for Blood. Gray has contributed to an additional fourth album, Unden!able. In 2012, Ryan Martinie toured with Korn as a temporary replacement for bassist Reginald Arvizu, who remained at home during his wife's pregnancy. The following year Martinie played bass on Kurai's debut EP, Breaking the Broken, and in 2014 Tribbett left Hellyeah. In a new interview with Songfacts in 2015, Gray said that Mudvayne's return seemed unlikely: "I don't know if the full band will [ever reunite]. Who knows -- they might be putting something else together. We were talking for a while and that whole thing with Greg [Tribbett's 2014 departure from Hellyeah] went down and everything kind of fell apart. Our relationship, which was the only truly solid relationship in the group, although Matt [McDonough] and I are still great, Ryan [Martinie] and I still briefly talk. I mean, the only way I personally would want to do Mudvayne is if everybody licked their wounds and got over it. There's a lot of things in that band that tore us apart. Maybe Mudvayne was the martyr for people that stopped supporting music. You sell 159,000 records the first week, and then the next record is like, 'Whatever, f--k it.' Maybe it's a subliminal message if you don't support things... Mudvayne's probably bigger now than it ever was. So, people want what they can't have." In 2015, former Mudvayne members Tribbett and McDonough formed the band Audiotopsy with Skrape vocalist Billy Keeton and bassist Perry Stern. Audiotopsy describes its sound as "progressive hard rock."
Question: Was there something specific that led to the breakup of the band?

Problem: Background: "Mr. Tambourine Man" is a song written, composed, and performed by Bob Dylan, who released his original version of it on his 1965 album Bringing It All Back Home. The Byrds also recorded a version of the song that they released in the same year as their first single on Columbia Records, reaching number 1 on both the Billboard Hot 100 chart and the UK Singles Chart, as well as being the title track of their debut album, Mr. Tambourine Man. The Byrds' recording of the song was influential in popularizing the musical subgenres of folk rock and jangle pop, leading many contemporary bands to mimic its fusion of jangly guitars and intellectual lyrics in the wake of the single's success.
Context: The Bringing it All Back Home version of "Mr. Tambourine Man" was included on Bob Dylan's Greatest Hits in 1967 and several later Dylan compilation albums, including Biograph, Masterpieces, and The Essential Bob Dylan. The two June 1964 recordings, one with Ramblin' Jack Elliott and the other at Witmark Music, have been released on The Bootleg Series Vol. 7: No Direction Home and The Bootleg Series Vol. 9: The Witmark Demos 1962-1964, respectively. Outtakes from the January 15, 1965 recording session were released on The Bootleg Series Vol. 12: The Cutting Edge 1965-1966 in 2015. The song has been in Dylan's live concert repertoire ever since it was written, usually as a solo acoustic song, and live performances have appeared on various concert albums and DVDs. An early performance, recorded during a songs workshop at the Newport Folk Festival on July 24, 1964 is included in both Murray Lerner's film The Other Side of the Mirror and the DVD release of Martin Scorsese's documentary No Direction Home. A live performance at New York's Philharmonic Hall dating from October 31, 1964, appeared on The Bootleg Series Vol. 6: Bob Dylan Live 1964, Concert at Philharmonic Hall. During his appearance at the Newport Folk Festival on July 25, 1965, after he was heckled by acoustic folk music fans during his electric set, Dylan returned to play acoustic versions of "Mr. Tambourine Man" and "It's All Over Now, Baby Blue"; this performance of "Mr. Tambourine Man" is also included in The Other Side of the Mirror. A live version from Dylan's famous May 17, 1966, concert in Manchester, England (popularly but mistakenly known as the Royal Albert Hall Concert) is included on The Bootleg Series Vol. 4: Bob Dylan Live 1966, The "Royal Albert Hall" Concert. Dylan's August 31, 1969 performance of the song at the Isle of Wight Festival appears on Isle of Wight Live, part of the 4-CD deluxe edition of The Bootleg Series Vol. 10: Another Self Portrait (1969-1971). Dylan also played the song as part of his evening set at the August 1, 1971, Concert for Bangladesh, a benefit concert organized by George Harrison and Ravi Shankar. That performance is included on The Concert For Bangladesh album, although it was excluded from the film of the concert. Another live version, from the Rolling Thunder Revue tour of 1975, is on The Bootleg Series Vol. 5: Bob Dylan Live 1975, The Rolling Thunder Revue, while electric band versions from 1978 and 1981 appear, respectively, on Bob Dylan at Budokan and the Deluxe Edition of The Bootleg Series Vol. 13: Trouble No More 1979-1981.
