A popular and prolific Spanish folk-metal outfit with a strong Celtic streak, Madrid's Mägo de Oz (Spanish for "Wizard of Oz") draw from a rich tapestry of hard rock subgenres, including symphonic, pagan, and power metal; they have issued no less than five rock operas. Playful and inventive, the band deftly weave elements of fantasy, satire, literature, witchcraft, and offbeat humor into their material (their name is Spanish for Wizard of Oz), with a metal umlaut tossed in for good measure. Since debuting with a self-titled album in 1994, the band have delivered increasingly ambitious conceptual pieces, with highlights arriving via the dystopian, two-part Finisterra (the latter one an opera) and the epic Gaia trilogy. Other seminal works include 2017's globally acclaimed Diabulus in Opera and 2021's Bandera Negra. This is a live album.
