Monday saw the premiere of Green Day’s newest single, the public’s first taste of an audacious album trilogy that will see its first installment, ¡Uno!, hit stores in September. As a longtime fan (Dookie and Nimrod practically soundtracked my high school years), I’ve had mixed feelings regarding the trio’s more ambitious post-American Idiot undertakings (increasingly ponderous music videos, a second rock opera LP, an honest-to-God Broadway musical). It’s laudable that Billie Joe Armstrong, Mike Dirnt, and Tre Cool are so intent on broadening their stylistic palette and challenging themselves creatively so far into their career, but the manner they’ve gone about it has felt increasingly stuffy and po-faced with each new “We’re an Important Band now” gesture. Luckily, Armstrong was quoted by Rolling Stone last month as saying, “The last record got so serious. We wanted to make things more fun”, which was a much-welcomed comment to hear after years of plodding ballads like “21 Guns” and “Wake Me Up When September Ends”.
