Background: Dethklok is a virtual death metal band featured in the Adult Swim animated television series Metalocalypse. The first official Dethklok album was released on September 25, 2007, entitled The Dethalbum. The album debuted at number 21 on Billboard Magazine's Top 200 list. The band released Dethalbum II on September 29, 2009, and toured with Mastodon, High on Fire and Converge.
Context: Voiced by: Tommy Blacha, Mike Keneally (singing voice in Metalocalypse: The Doomstar Requiem) Toki Wartooth is Dethklok's rhythm guitarist. He typically played a Gibson Flying V, but has switched to the Brendon Small "Snow Falcon" V for the fourth season. A native of "an abandoned town near Lillehammer", Norway, he was forced to constantly perform manual labor by his abusive parents. He has a distinct accent and often inappropriately pluralizes words, but refers to Pickles as "Pickle". Visually, he has a distinct Fu Manchu moustache, long brown hair, and very pale blue eyes. Toki is the only Dethklok member with no prior band experience, as well as the only one not with the band in its initial form, having been chosen to replace the violent and egomaniacal Magnus Hammersmith. Small explains Toki's relationship with Skwisgaar as "...Norwegian to Skwisgaar's Swedish, pompous attitude. And, again, a second-class citizen in the same band", and compared his guitar playing style to that of Iron Maiden. In contrast to the deep cynicism, grim outlook, promiscuity, and alcohol and drug abuse of the other band members, Toki's character is generally childlike, innocent, and good-natured. He has a boyish bedroom complete with action figures, stuffed animals, and wall posters, and a prominent hobby of his is building model planes. He is a Type 2 diabetic and requires insulin shots. A recurring plot point is the death of people Toki grows fond of, including a guitar teacher and his father; the Tribunal has described him as an "angel of death". Any living thing that gets close to Toki - with the exception of Dr. Rockso and his bandmates - tends to die after a brief period of time.

Problem: Background: Symphony X is an American progressive metal band from Middletown, New Jersey. Founded in 1994, the band consists of guitarist Michael Romeo, keyboardist Michael Pinnella, drummer Jason Rullo, lead vocalist Russell Allen and bassist Michael Lepond. They achieved some commercial success with the 2007 album Paradise Lost and the 2011 album Iconoclast, which reached number 76 on the Billboard 200. Romeo explained the band's name in a 2008 interview; "So, you know, the music we were coming up with had the keyboard thing and the guitar, and some classical elements, so the word 'Symphony' came up and, so the dramatic thing, you know?
Context: On March 1, 2010, an update on the Symphony X official website announced, that the band had recorded most of their next album and that Romeo and Allen were working on lyrics; Romeo was getting ready to start doing tracking for the album. The album's name and lyrical concept were revealed on January 29, 2011 in an interview by DJ JC Green of Metal Messiah Radio's "Heavy Metal Thunder" show with Russell Allen: the follow-up to Paradise Lost will be titled Iconoclast and will have its lyrics centered around "machines taking over everything and all this technology we put our society into pretty much being our demise." On March 25, 2011, it was announced on the Nuclear Blast website and Blabbermouth.net, that the new Symphony X album, Iconoclast, would be released in Europe on June 17 and in North America on June 21, as a Standard Edition as well as a 2-CD Digipack. Iconoclast debuted at number 76 on the Billboard 200 album chart in the United States, selling more than 7,300 copies in its first week. The record also debuted at number 7 on the Top Hard Rock Chart, number 19 on the Top Rock Chart and number 13 on the Top Independent Chart. The album showcases the highest chart position and the most first-week sales in the band's history. On February 25, 2011, Symphony X played the first show of their 2011 tour in Stuttgart, Germany, where they performed two songs from Iconoclast: "End of Innocence" and "Dehumanized". Some days later, in Antwerp, Belgium, they performed yet another new song, "Heretic". During their show in London, England, the band debuted another new song titled "Prometheus". On February 27, 2013, it was announced that, during the previous week, drummer Jason Rullo was admitted to hospital for heart failure. Jason spent a week in hospital, and was released after some days. He then started a rehab program that took a minimum of 3-6 months under doctors' care. John Macaluso joined them on tour for their South American and European dates, until Jason Rullo was able to fully recover.
