Björk Guðmundsdóttir (born 21 November 1965), known mononymously as Björk (), is an Icelandic experimental singer, songwriter, multi-instrumentalist, producer and occasional actress. She initially became known as the lead singer of the alternative rock band The Sugarcubes, whose 1987 single "Birthday" was a hit on US and UK indie stations and a favorite among music critics. Björk began her career as a solo artist in 1993. Her album Debut was rooted in electronic, house, jazz and trip hop and is widely credited as one of the first albums to introduce electronic music into mainstream pop. Over her three-decade solo career, Björk has developed an eclectic musical style that incorporates aspects of electronic, alternative dance, trip hop, experimental, jazz, alternative rock, avant-garde and classical music.
