Epic Sax Guy began at the Eurovision Song Contest 2010, where saxophonist Sergey Stepanov performed with Moldova's SunStroke Project on the song Run Away. A short clip of his hip swinging solo was looped on YouTube and spread as a reaction and celebration meme, often in ten hour edits. Stepanov returned to Eurovision in 2017, cementing the joke. Remixes like the Cruzo version tightened the loop into a short, punchy alert sound that streamers and editors still reuse.
