Since 2011, Sunstroke Project has toured extensively and has worked more closely with their longtime label, Sens Music. An entry was made for SunStroke Project and Olia Tira to represent Moldova in the 2012 Eurovision Song Contest with the single "Superman" but it did not make the next stage of selection. SunStroke Project attempted to represent Moldova in the 2015 Eurovision Song Contest entering with two songs: "Lonely" and "Day After Day", the latter with Michael Ra. Both entries qualified to the semi-final from the live audition round. However, as only one song could be chosen per artist, Sunstroke Project chose "Day After Day" to ultimately move forward. After qualifying from the semi-final, they finished third in the national final. SunStroke Project attempted to represent Moldova in the 2017 Eurovision Song Contest once again, with the upbeat electro-house song "Hey, Mamma!". The band came in first place after a tight voting procedure, qualifying them to represent Moldova in the Song Contest in May. They reached third place with their performance in the 2017 competition, giving Moldova their best result in the contest. On returning to Moldova, SunStroke Project was awarded the Order of Honour by the President of Moldova Igor Dodon. Sunstroke Project were also featured in Season 2 of the Netflix series, "Travels With My Father," wherein British comedian Jack Whitehall travels to Moldova with his father, Michael Whitehall, in order to meet and perform with the members of Sunstroke Project.
