music for "Split Sides", a dance piece by the Merce Cunningham Dance Company, which debuted in October 2003 at the Brooklyn Academy of Music. Radiohead's sixth album, Hail to the Thief, was released in June 2003. Its lyrics were influenced by what Yorke called "the general sense of ignorance and intolerance and panic and stupidity" following the 2000 election of US President George W. Bush. The album was promoted with a website, radiohead.tv, where short films, music videos, and studio webcasts were streamed. Hail to the Thief debuted at number one in the UK and number three on the Billboard chart, and was eventually certified platinum in the UK and gold in the US. The singles "There There", "Go to Sleep" and "2 + 2 = 5" achieved heavy circulation on modern rock radio. At the 2004 Grammy Awards, Radiohead were again nominated for Best Alternative Album, and Godrich and the engineer Darrell Thorp received the Grammy Award for Best Engineered Album. In May 2003, Radiohead embarked on a world tour and headlined Glastonbury Festival for the second time. The tour finished in May 2004 with a performance at the Coachella Festival in California. A compilation of Hail to the Thief B-sides, remixes and live performances, Com Lag (2plus2isfive), was released in April 2004. Hail to the Thief was Radiohead's final album with EMI; in 2006, The New York Times described Radiohead as "by far the world's most popular unsigned band". Following the Hail to the Thief tour, Radiohead went on hiatus to spend time with their families and work on solo projects. Yorke and Jonny Greenwood contributed to the Band Aid 20 charity single "Do They Know It's Christmas?", produced by Godrich. Greenwood composed soundtracks for the films Bodysong (2004) and There Will Be Blood (2007); the latter was the first of several collaborations with the director Paul Thomas Anderson. In July 2006, Yorke released his debut solo album, The Eraser, comprising mainly electronic music. He stressed it was made with the band's blessing, and that Radiohead were not breaking up. Jonny Greenwood said: "He had to get this stuff out, and everyone was happy [for Yorke to make it] ... He'd go mad if every time he wrote a song it had to go through the Radiohead consensus." 2006–2009: Departure from EMI, In Rainbows, and "pay what you want" Radiohead began work on their seventh album in February
