SunStroke Project is a Moldovan musical group composed of Sergei Yalovitsky, Sergey Stepanov (saxophonist), and previously Anton Ragoza until his departure in 2019. They achieved recognition after representing Moldova in the Eurovision Song Contest 2010 alongside Olia Tira with the song "Run Away", and again in the 2017 contest with "Hey Mamma", finishing in third place in the latter. The name of the group was chosen by Ragoza whilst working in the army with Stepanov, after he had an incident in which he was affected by heat stroke whilst on a field exercise.

Moldova participated in the Eurovision Song Contest 2017 with the song "Hey Mamma" written by Anton Ragoza, Sergei Ialovitski, Sergey Stepanov, Mihail Cebotarenco and Alina Galetskaya. The song was performed by the group SunStroke Project. The Moldovan broadcaster TeleRadio-Moldova (TRM) organised the national final O melodie pentru Europa 2017 in order to select the Moldovan entry for the 2016 contest in Kyiv, Ukraine. 40 entries competed to represent Moldova in Kyiv, with 14 being shortlisted to participate in the televised national final after auditioning in front of a jury panel. After a semi-final and final which took place on 24 and 25 February 2017, "Hey Mamma" performed by SunStroke Project emerged as the winner after gaining the most points following the combination of votes from a jury panel and a public televote.
