Artūrs Šingirejs was born on 10 April 1984 in Brocēni, Saldus district, Latvia to a Belarusian father and a Latvian mother, who performed professionally as a soloist in the Liepāja group Santa, led by Zigmars Liepiņš. His father was also an amateur singer who performed on the guitar; he credits his parents as being his main teachers. He has one brother and three sisters, one of whom was the first to encourage him to perform on stage at the age of four. He said about being the fourth child, "...gave me freedom: I was the fourth child in the family and I got it even more than the others. Freedom gave me the courage to dream". His mother taught him English from the age of six and he credits Freddie Mercury as one of his first musical idols. He studied piano at the Saldus Music School. He had his first solo performance at age 16 and stated, "My first performance was at school, and I realized that I wanted to do this - there is something here that binds me". He later studied culinary arts before returning to music as a profession. He learned to play the guitar and sing through self-study.

Dons gained popularity in 2003 by participating in the Latvian reality show Talantu Fabrika (lit. 'Talent Factory'). During the show, he met and dated fellow contestant Lily (real name Linda Kalniņa). He joined Radio SWH Rock as a DJ host after winning the reality show, which he says was much more stressful than performing on stage. Dons and Lily released an English language duet album in 2004, Viens Otram (lit. 'To Each Other'). The album became a best seller in Latvia and they earned a nomination for Top Radio Hit with "Just For You" at the 2003 Latvian Music Recording Awards. In 2004, his song "Ja es būtu vējš" (lit. 'If I Were The Wind') was nominated for Top Radio Hit at the Latvian Music Recording Awards. After the success of the duet album, Dons focused on a solo career, releasing his first solo album (mostly in English) Lights On in 2006. The album was nominated for Best Rock Album and his single, "Lights Out" was nominated for Best Rock Song at the 2006 Latvian Music Recording Awards.

Afterwards, he moved between London and Los Angeles with Lily, saying in interviews at the time that she was his muse and source of inspiration; they married in 2009. While living abroad, he adopted and subsequently abandoned several stage names; first he used Art Green and later went by Art Singer while in the United States. Dons later commented on his numerous names, "Call me whatever you want. I have a lot of names. The name Art Singer I use in England is an abbreviated name. Art Green was the predecessor of Art Singer, but I somehow didn't feel that name... In Latvia I'm known more as Dons, which I chose myself. That nickname came in and dragged me along and I get along with it well". While in Los Angeles, he received four offers to be the lead singer in various rock bands.

In 2007, he performed in Zigmars Liepiņš' popular musical theatre Adata with the song "Ja Tu Man Esi" ("lit. 'If I Have You'"). The song was nominated for Top Radio Hit at the Latvian Music Recording Awards that year.

In 2008, Dons released his second solo album, Lelle (lit. 'Doll'), which was his first Latvian language album. The album was the first of many where he collaborated with lyricist Ingus Bērziņš. It won the Best Rock Album in the Latvian Music Recording Awards that year. The success of the album proved his audience preferred his music performed in Latvian over his English language music. He represented Latvia at the New Wave 2008, where he got 4th place.
