What is "xx"

adj. denoting a quantity consisting of 20 items or units [syn: twenty, 20]

XX may refer to:

XX (pronounced Double X) is the fourth album and the first on a major label by the alternative metal band Mushroomhead, released in 2001. It was originally released through Eclipse Records, where Mushroomhead took classic tracks and re-recorded them. XX was entirely re-recorded and re-released on Universal Records later in the year. XX contains tracks from the band's three independently released albums – Mushroomhead, Superbuick and M3.

XXs re-release on Universal Records introduced Mushroomhead on a national and international level, while previously being just a regionally known band. The album has sold over 300,000 copies. Musically, the album fuses alternative metal with a diverse array of genres, including industrial music, gothic rock, punk rock, techno and hip hop.

The XX or simply The 20 are a fictional organization in both the XIII comic and game.

xx is the debut album by English indie pop band the xx. After they signed a contract with XL Recordings, the band recorded the album from December 2008 to February 2009 at the record label's in-house studio in London. Audio engineer Rodaidh McDonald worked with the xx during the recording sessions and strived to reproduce the intimate, unembellished quality of their demos. The band's Jamie Smith produced xx on his laptop and created electronic beats for the songs, which he then mixed in a detailed process with McDonald.

Although the xx had been strongly influenced by R&B acts, the album drew comparisons from critics to alternative rock, electronica, and post-punk sounds. The melancholic songs on xx featured minimalist arrangements and were built around Smith's beats, Oliver Sim's basslines, and sparse guitar figures played by Baria Qureshi and Romy Madley Croft, who employed reverb in her lead guitar parts. Most of them were sung as low-key duets by Croft and Sim, both of whom wrote emotional lyrics about love, intimacy, loss, and desire.

xx was released in August 2009 by Young Turks, an imprint of XL, and received widespread acclaim from critics, many of whom named it one of the year's best records. It sold consistently over its first few years of release, becoming a sleeper hit in the United Kingdom and the United States. Although none of its singles became hits, xx benefited commercially from the licensing of its songs to television programs and the band's Mercury Prize win in 2010. When Qureshi was dismissed from the group shortly after the album's release, they continued to play as a trio on a protracted concert tour that helped increase their fanbase, reputation in the press, and confidence as performers.

XX is a compilation by Great Big Sea to celebrate the band's 20th anniversary. It is the group's final album to date, as well as their last recording to feature Séan McCann. It was released as a two-disc CD album, and also in a Deluxe Edition which includes a third CD plus a DVD with an hour-long documentary "Meet Great Big Sea" and other goodies.

The XX Tour was a comprehensive tour which accompanied the release of this album, playing 38 shows across North America and featuring music from almost all previous Great Big Sea records. This tour began on March 5, 2013 with a show at The Grove in Anaheim, California, and concluded a few minutes after midnight on January 1, 2014, after a final New Year's Day concert at Casino New Brunswick in Moncton. Following the XX Tour, Séan McCann officially withdrew from the band.
