Icelandic singer and songwriter Björk has recorded more than one hundred songs for eight studio albums, two soundtrack albums, a compilation album, five remix albums and two collaboration albums. She is the sole writer and producer of most of the songs included in her albums. She also sometimes plays instruments during her recording sessions. Moreover, she has provided credited and uncredited contributions on songs recorded by other artists, including background vocals, songwriting, remixing and production.
After enrolling at the Barnamúsíkskóli in Reykjavík, she started developing an interest in writing and performing. A recording of her rendition of Tina Charles' 1976 song "I Love to Love", sung when she was 10 years old, led to the signing of a record deal with Fálkinn. Her first eponymous solo release (1977), nowadays considered juvenilia, consisted of cover songs. Nonetheless, the album included her first composition, "Jóhannes Kjarval". Thereafter, Björk ventured into music bands experiences, singing as the lead voice of groups like Tappi Tíkarrass, Kukl, The Elgar Sisters and, most notably, The Sugarcubes. While recording with The Sugarcubes, Björk appeared as a background vocalist for fellow artists like Megas, Current 93 and Bless, and some of her original music was included in local music compilations. In 1990 she released Gling-Gló alongside Tríó Guðmundar Ingólfssonar, a cover album of Jazz standards.
