Sascha Röntgen[1] (né Schmitz; born 5 January 1972), better known by his stage name Sasha, is a German singer, songwriter, and occasional actor.

Raised in a Christian home alongside his younger brother Norman (born 1976), Sasha spent his childhood in Soest, North Rhine-Westphalia, following his parents' divorce.

[4] Although the band was never offered a recording contract, they played live all over their area, resulting in occasional busking sessions with his friend Benedict, with whom he also performed as the 'Hin und Hair Schmitz' duo.

While the band broke up shortly thereafter, Grant and Di Lorenzo recognized his singing talents and hired Sasha as a backing vocalist for several of their projects.

[4][5][6] During the following years, Sasha earned his money as a background singer for several artists, including virtual euro-dance projects H.I.M and Sir Prize, whose singles "Lookin' Out 4 Luv" and "Don't Go Away" were released in German-speaking Europe, but led to short promotional tours in Tunisia.

The song became a top ten hit in Central Europe and resulted in a second collaboration, entitled "Wanna Be Your Lover", on which he received his first credited solo part and filmed a music video for.

[9] The track was followed by "If You Believe", which would become his highest-charting single to date and reached the top five in Austria, Belgium, Germany, the Netherlands, and Switzerland, receiving one platinum and four gold discs.

[10] A "blend of romantic ballads and quicker funk- and reggae-inspired tracks", according to Billboard, the album was eventually released in fall 1998 and sold more than 400,000 copies in Germany alone.

[13] Inspired by Nick Cave & the Bad Seeds and originally conceived as a humorous lark (Sasha and his fellow musicians André "Adriano Batolba" Tolba, Maik "Mike Scott" Schott, Felix "Phil X Hanson" Wiegand and Martell "Matt L. Hanson" actually "acted" as their alter egos on-stage and during interviews),[13] the quintet recorded a whole album together, including re-arranged cover versions of songs such as Pink's "Get the Party Started", George Michael's "Freedom", and Michael Jackson's "Black or White".

In 2006, Sasha made his big screen debut with a small role in the German comedy film Goldene Zeiten, directed by Peter Thorwarth.
