Though its songs including the Top 10 singles American Idiot, Boulevard of Broken Dreams, and Wake Me Up When September Ends were inspired by the post-9/11 political climate  – particularly the Iraq War, the ascendancy of George W. Bush and mass media propaganda – now in the social media age two decades later, particularly amid the current turbulence in both the album’s homeland and our own UK political landscape, American Idiot’s social commentary and howls of discontent could be considered timeless.

Reacting to the news, Green Day said: “We made American Idiot as a protest album – against fear, against lies, against apathy. But also a character driven concept album. It was risky, it was loud, it was personal – and it changed everything for us. Twenty years later, the fact that it still resonates means the world and we’re very proud that it continues to inspire people everywhere.”

Martin Talbot, Chief Executive, Official Charts says: “We are delighted to use National Album Day’s celebration of rock to throw the spotlight on the heavier end of the spectrum – and acclaim Green Day’s American Idiot as the biggest heavy rock studio album of the 21st century.  

“It is remarkable that, more than 20 years after its release, the album’s message of generational disillusionment is as relevant as it ever was. Its enduring power underlines the importance of music as a reflection of and reaction against the political temperature of our times.” 

The album’s title track sees front man Billie Joe Armstrong sing “Don’t want to be an American idiot, one nation controlled by the media”,  20 years on, the “age of hysteria” that Armstrong referenced back in the early 00s, along with the record’s themes of fear, disillusion with government, corporate control and propaganda, couldn’t be more poignant to revisit and debate all over again this National Album Day.
