input: Touring internationally in June and July, the Beatles staged 37 shows over 27 days in Denmark, the Netherlands, Hong Kong, Australia and New Zealand. In August and September they returned to the US, with a 30-concert tour of 23 cities. Generating intense interest once again, the month-long tour attracted between 10,000 and 20,000 fans to each 30-minute performance in cities from San Francisco to New York.  In August, journalist Al Aronowitz arranged for the Beatles to meet Bob Dylan. Visiting the band in their New York hotel suite, Dylan introduced them to cannabis. Gould points out the musical and cultural significance of this meeting, before which the musicians' respective fanbases were "perceived as inhabiting two separate subcultural worlds": Dylan's audience of "college kids with artistic or intellectual leanings, a dawning political and social idealism, and a mildly bohemian style" contrasted with their fans, "veritable 'teenyboppers' - kids in high school or grade school whose lives were totally wrapped up in the commercialised popular culture of television, radio, pop records, fan magazines, and teen fashion. To many of Dylan's followers in the folk music scene, the Beatles were seen as idolaters, not idealists." Within six months of the meeting, according to Gould, "Lennon would be making records on which he openly imitated Dylan's nasal drone, brittle strum, and introspective vocal persona"; and six months after that, Dylan began performing with a backing band and electric instrumentation, and "dressed in the height of Mod fashion". As a result, Gould continues, the traditional division between folk and rock enthusiasts "nearly evaporated", as the Beatles' fans began to mature in their outlook and Dylan's audience embraced the new, youth-driven pop culture.  During the 1964 US tour, the group were confronted with the reality of racial segregation in the country at the time, particularly in the South. When informed that the 11 September show at the Gator Bowl in Jacksonville, Florida was to be held at a segregated venue, the Beatles expressed astonishment and announced that they would refuse to perform unless the show become integrated. Lennon stated: "We never play to segregated audiences and we aren't going to start now ... I'd sooner lose our appearance money." The group's stand drew controversy in the local media, but city officials relented and agreed to allow an integrated show. On the tour the group also refused to stay in segregated hotels. Documents reveal that for their subsequent US tours in 1965 and 1966, the Beatles included clauses in contracts stipulating that shows be integrated.

Question: 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?

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.

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".
