Sergey Igorevich Stepanov, commonly known as the Epic Sax Guy, Saxroll or Ultra Sax Guy, is a Moldovan musician and composer and a member of the SunStroke Project.

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.
