Yusuf Islam (born Steven Demetre Georgiou; 21 July 1948), commonly known by his stage name Cat Stevens, and later Yusuf, is a British singer-songwriter and multi-instrumentalist. His musical style consists of folk, pop, rock, and, in his later career, Islamic music. He was inducted into the Rock and Roll Hall of Fame in 2014.His 1967 debut album and its title song "Matthew and Son" both reached top ten in the UK charts. Stevens' albums Tea for the Tillerman (1970) and Teaser and the Firecat (1971) were certified triple platinum in the US. His 1972 album Catch Bull at Four spent weeks at the top of several major charts. He earned ASCAP songwriting awards in 2005 and 2006 for "The First Cut Is the Deepest", and the song has been a hit for four artists. His other hit songs include "Father and Son", "Wild World", "Moonshadow", "Peace Train", and "Morning Has Broken".
In December 1977, Stevens converted to Islam and adopted the name Yusuf Islam the following year. In 1979, he auctioned all of his guitars for charity. He has since bought back at least one of these guitars as a result of the efforts of his son Yoriyos, and left his musical career to devote himself to educational and philanthropic causes in the Muslim community. He was embroiled in a long-running controversy regarding comments he made in 1989 about the death fatwa on author Salman Rushdie. He has received two honorary doctorates and awards for promoting peace as well as other humanitarian awards.
In 2006, he returned to pop music – releasing his first new studio album of new pop songs in 28 years, entitled An Other Cup. With that release and subsequent ones, he dropped the surname "Islam" from the album cover art – using the stage name Yusuf as a mononym. In 2009, he released the album Roadsinger and, in 2014, he released the album Tell 'Em I'm Gone and began his first US tour since 1978. His second North American tour since his resurgence, featuring 12 shows in intimate venues, ran from 12 September to 7 October 2016. In 2017, he released the album The Laughing Apple.
