One Direction デラックス・エディション, ワン・ダイレクション
English-Irish teen-pop boy band formed during the British TV singing competition "The X Factor" in 2010. They finished third in the series and subsequently signed with Simon Cowell's label Syco Music. In November 2011 they released their debut album "Up All Night". The album went straight to number one on the US Billboard 200 chart, which made One Direction the first UK group in US chart history to debut at number one with their first album. In March 2015, Zain Malik left the group, which came as a big surprise and disappointment for both the remaining members and the group's worldwide fan base, known as Directioners.
