Founded in 1999 by drummer Txus di Fellatio -- the band has hosted dozens of different musicians over the years -- the first iteration of the group solidified in 1992 under the moniker Transilvania. A strong showing in the Rock de Villa de Madrid contest prompted a name change, and in 1994 they released their eponymous debut album as Mägo de Oz. A period of personnel upheaval preceded the release of the group's sophomore effort, Jesús de Chamberí, a rock opera about Jesus returning to the Madrid neighborhood of Chamberí. That album, along with La Bruja -- an EP stocked with five re-recorded songs featuring a new lead vocalist -- greatly increased the band's profile. A modern retelling of Miguel de Cervantes' Don Quixote, La Leyenda de La Mancha arrived in 1998, followed in 1999 by Resacosix en Hispania, a film celebrating the group's tenth anniversary.
The band doubled down on the conceptual route for 2000's Finisterra, a two-volume set concerning a fictional digital dystopia, and again in 2003 with the release of the ambitious Gaia, the first installment of a trilogy about the Spanish conquest of America and the ecological damage caused by mankind, which continued in 2005 with Gaia II: La Voz Dormida and concluded in 2010 with Gaia III: Atlantia and the ancillary Gaia Epílogo. In between the latter offerings, the group issued the stand-alone studio album La Ciudad de los Árboles and the concert LP A Costa da Morte. Hechizos Pocimas y Brujerias arrived in 2012, and was the first Mägo de Oz outing for new vocalist Zeta; he replaced longtime frontman José Andrëa who'd left the fold the year prior. Ilussia, the band's circus-themed 12th studio long-player, was released in 2014, followed in 2015 by Finisterra Opera Rock, a re-recording of the group's 2000 release that featured numerous collaborations. Diabulus in Opera, a sprawling live album/video, was issued in 2017. Two years later that band returned with Ira Dei, a biblical and apocalyptic concept LP. ~ James Christopher Monger, Rovi
