Question: What was the first award that Iron Maiden received from the Metal Hammer Golden Gods Awards? Passage:In 1994, one of their singles, "Fear of the Dark", received a Grammy nomination for Best Metal Performance. Seven years later, the band were nominated again in that category, with the song "The Wicker Man". In 2011, Iron Maiden won the award with "El Dorado". In 2002, they won the Ivor Novello Award for international achievement. Iron Maiden received a nomination from the Kerrang! Awards in the "Best Live Act" category in 2003, and were inducted into the Kerrang! Hall of Fame two years later. At the 2006 Metal Storm Awards, A Matter of Life and Death was named the best heavy metal album of the year. Iron Maiden have also received nine awards from fourteen nominations at the Metal Hammer Golden Gods Awards. Their mascot Eddie, who has previously been used by US critics to argue that Iron Maiden are Satanists, received a Golden Gods nomination in 2006, losing to singer Cristina Scabbia; but was awarded in 2008. Later in 2008, Iron Maiden were nominated in the Best Live Return category at the Vodafone Live Music Awards, to which the band disagreed with their nomination and asked to be withdrawn, stating that they were "not quite sure where we are returning from." They were replaced by the band James. The band were named "Best British Live Act" at the 2009 BRIT Awards, winning via a public poll. They were not able to attend the ceremony, ironically due to touring duties, instead delivering an acceptance message by video link-up. Their film won, in the category "24 Beats Per Second", at the SXSW film Festival, held in Austin, Texas, in March 2009. Overall, Iron Maiden have received twenty-nine awards from thirty-nine nominations.
