[1] In an interview, she stated that a number of her material was written as therapy, including "Verde împărat" and her 2016 single "Cine m-a făcut om mare" ("Who Made Me Big").

[5] She also sang "Verde împărat" during her three–day concert tour Psihedelia at Sala Palatului in Bucharest, Romania, on a piano covered with moss[1][6] followed by its digital release on 23 October 2017 by Cat Music.

[7] "Verde împărat" is a Romanian language liquid dubstep and chillout song, acting as a departure from the singer's past pop and dance material.

Alex Stănescu from InfoMusic called the song unique and praised Delia's vocal performance,[1] while Alexandra Cheroiu, writing for Adevărul, positively saw it as different from her past work.

"[5] An accompanying music video for "Verde împărat" was shot by Alex Ceauşu in early October 2017 — with whom Delia had collaborated in the past for her visuals for the 2016 and 2017 singles "1234 (Unde dragoste nu e)" ("1234 (Where There Is No Love)") and "Rămâi cu bine" ("Fare You Well") — while post-production was handled by Cristi Smarandoiu and Cristian Bălan.

[8] The clip references Romanian fairy tales and features various shots of Delia wearing nature-inspired outfits, a multicolored wig and dressed like the Snow Queen in a "charmed" forest.
