Task: Question Answering
Input (English): Passage: Radiohead began work on their ninth studio album in September 2014, joined again by Godrich. In 2015 they resumed work in the La Fabrique studio near Saint-Rémy-de-Provence, France. The sessions were marred by the death of Godrich's father, and Yorke's separation from his wife, Rachel Owen, who died of cancer several months after the album's completion. In the same year, Yorke contributed a soundtrack, Subterranea, to The Panic Office, an installation of Radiohead artwork in Sydney, Australia, and Junun, a collaboration between Greenwood, Godrich, Israeli composer Shye Ben Tzur and Indian musicians, was released, accompanied by a documentary directed by Anderson. On Christmas Day 2015, Radiohead released a new song, "Spectre", on the audio streaming site SoundCloud. It had been commissioned for the 2015 James Bond film Spectre, but was rejected by the film producers as "too dark".Radiohead's ninth studio album, A Moon Shaped Pool, was released in May 2016 on Radiohead's website and online music stores, followed by retail versions in June via XL Recordings. It was promoted with music videos for the singles "Burn the Witch" and "Daydreaming", the latter directed by Anderson. The album includes several songs written years earlier, including "True Love Waits", and strings and choral vocals arranged by Jonny Greenwood and performed the London Contemporary Orchestra. It was Radiohead's sixth UK number-one album and reached number three in the US. It was the fifth Radiohead album nominated for the Mercury Prize, making Radiohead the most shortlisted act in the award's history, and was nominated for Best Alternative Music Album and Best Rock Song (for "Burn the Witch") at the 59th Annual Grammy Awards. It appeared on several publications' lists of the best albums of the year.
