You don't become one of the biggest bands on this planet - selling 15 million albums worldwide, five MTV Europe Awards, two Brit Awards, eight NME Awards, five Q Awards, four Kerrang! Awards, and winner of the 2011 Best Rock Album Grammy; No 1 in 19 countries with 2009's The Resistance; filler of arena and stadiums across the world - by sitting on your hands. So when Muse approached the making of their sixth studio album, The 2nd Law, they wouldn't skimp on the choirs, strings, and horn sections. And rest assured: guitar-shredding, piano-thumping, orchestra-arranging, book-chewing, big-thinking Matt Bellamy, as the band's chief songwriter, didn't lower his sights from The Big Picture nor ignore The Precious Details. Nor were the trio afraid of giving space to a brilliant new element to their sound - songs written and sung by bass player Chris Wolstenholme. It was about saving themselves aggravation and conserving energy. And, appropriately, it was about The 2nd Law: an album named after and thematically influenced by the Second Law of Thermodynamics, which concerns the inevitable wasting of energy within a closed system. It was about letting themselves go and enjoying themselves. Muse, after all, had earned it.
