Originally released in 2010, Iron Maiden's fifteenth studio album, The Final Frontier was released an incredible 30 years after the band's game-changing self-titled debut in 1980. The release also marked the band's first since 2006's A Matter of Life and Death which was the longest gap between any Maiden studio release until its 2015 follow-up. Reuniting with long-time producer Kevin 'Caveman' Shirley at Compass Point Studios in the Bahamas, the 10-song set mixes up-tempo rock numbers with more groove oriented material, all with Maiden's signature British heavy metal imprint. The Final Frontier went on to become the biggest commercial success of the band's career, reaching No. 1 in 40 countries worldwide. The track "El Dorado" also won a 2011 Grammy Award for Best Metal Performance which was the band's first Grammy win.
