on the Billboard 200 albums solely through its digital sales. On August 26, Asthmatic Kitty announced that Stevens would release his newest full-length album, The Age of Adz, on October 12. NPR streamed the album until it was released on October 12, 2010. The two albums featured a wide range of arrangements, from orchestral to electronic. Song lengths were also extended; the track "Djohariah" from All Delighted People is 17 minutes long, while "Impossible Soul" from The Age of Adz is 25 minutes long. The albums also feature many styles from disco to folk. Stevens has stated in interviews that in 2009 and 2010 he suffered from a mysterious debilitating virus infection that affected his nervous system. He experienced chronic pain and was forced to stop working on music for several months. He said: "The Age of Adz, is, in some ways, a result of that process of working through health issues and getting much more in touch with my physical self. That's why I think the record's really obsessed with sensation and has a hysterical melodrama to it." On October 12, 2010, Stevens began his North American tour in Montreal, featuring virtually all new material. The tour lasted just over a month and ended on November 15, 2010, in New York City. Stevens toured Australia and New Zealand in early 2011, featured as part of the Sydney Festival, and appeared on-stage with The National during the last of three sold-out Auckland shows. He also toured Europe and the United Kingdom in April and May 2011, playing there for the first time in five years. His shows mostly consisted of new material, but he did play many older tracks from Seven Swans and Illinois. Stevens ended the Age of Adz tour with two shows in Prospect Park, Brooklyn, New York. Further collaborative projects (2012–2014) On February 27, 2012, it was announced Stevens would release a collaborative EP titled Beak & Claw, on March 20, with artists Son Lux and Serengeti under the name S / S / S on the Anticon record label. Stevens released a 7" with close friend Rosie Thomas for Record Store Day 2012, titled Hit & Run Vol. 1. He also collaborated with choreographer Justin Peck on two ballets for the New York City Ballet: Year of the Rabbit (2012) and Everywhere We Go (2014), both to great critical acclaim.
