Radiohead have a history of taking a stand one stanza and guitar riff at a time. They questioned the morality of capitalism and a ''plastic" culture on their seminal album, The Bends (1995) - lead singer Thom Yorke crooned in the song Fake Plastic Trees about ''a town full of rubber plans". Now 11 years later, with the release of their ninth studio album A Moon Shaped Pool, Yorke and his band are still left with questions.The first single, Burn the Witch, has been taken by some as a warning against group brainwashing and right-wing politics. This interpretation is amplified by the stop-frame animation video which harks back to the 1970s British children's TV show about a small village, Trumptons.The fact that we face the possibility of America becoming a small-minded town of "Trump"ton has not been lost on the scores of fans on social media.The animator who led the team that handmade each frame of the video, Virpi Kettu, told Billboard magazine that she understood the song to be about raising awareness about the refugee crisis in Europe, referencing the lyrics "Abandon all reason / avoid all eye contact / Do not react."The video shows smiling Plasticine people dunking ''witches", performing pagan rituals and burning the wooden effigies of strangers.Xenophobia isn't the only thing the new album tackles. In The Numbers , the lyrics urge people to reali se that "People have this power / The numbers don't decide / Your system is a lie". They seem to be criticising climate change.Radiohead's latest video - for the single Daydreaming - was directed by Paul Thomas Anderson, who directed There Will be Blood .In it a disorientated Yorke runs aimlessly through laundromats and hotels singing the words "Efil ym fo flah" (translated as "Half of my life"). This is a reference to his divorce. He was with his wife for 23 years, half his life.A Moon Shaped Pool is two hours and 40 minutes worth of cynicism-free messages of foreboding - songs that tell stories of a dark future, which may portend their most truthful message yet.Radiohead's A Moon Shaped Pool is available on iTunes...
