Sharon Janny den Adel (born 12 July 1974, in Waddinxveen, South Holland, Netherlands) is a Dutch singer and composer, best known as the lead vocalist and one of the main songwriters in the Dutch symphonic metal/rock band Within Temptation. She has performed with various bands since she was 14, including a blues rock band called Kashiro, before forming Within Temptation with Robert Westerholt in 1996.

Together with her partner, Robert Westerholt, den Adel is one of the founding members of Within Temptation. She has defined their work as epic and cinematic. Her vocals play a major role in the band's sound, despite having never received formal vocal training. Den Adel sings in the mezzo-soprano range but her vocal quality is light and lyric despite her range. Before Within Temptation became famous, she worked for a fashion company, leaving after the band found success with their hit single "Ice Queen". She utilises her fashion expertise by designing her stage costumes and the band's merchandise.About.com described den Adel as a "versatile and skilled singer who is equally adept at singing powerfully with a full orchestra and choir as she is at singing quietly and emotionally with just a piano."

Robert Westerholt (born 1 January 1975, Waddinxveen, South Holland, Netherlands) is a Dutch musician, known as the guitarist, backing vocalist and co-founder of the symphonic metal band Within Temptation. He also writes music for the band, along with the band's vocalist, and his partner, Sharon den Adel. He used to work in human resource management before his career with Within Temptation.

In 1992, Westerholt formed the band "The Circle" with future Within Temptation keyboard player Martijn Spierenburg, and he began writing his own music. The Circle's first demo, entitled 'Symphony No.1' was finished in December 1992. At this point, The Circle had a complete line-up, composed of Westerholt, Martijn, Jeroen Van Veen (Within Temptation's bassist), Arjan Groenedijk and Ernst Van Der Loo, although Arjan and Ernst both left the band a while later. In a 1995 compilation album released by DSFA Records two songs, "Broken Silence" and "Frozen"by The Circle were featured. Soon afterwards, Westerholt left The Circle, and the band was renamed as Voyage. Voyage released their only album 'Embrace' in 1995, in which Sharon den Adel collaborated on the track "Frozen".
