Along with the signing, Software announced the release of his debut EP, Remembrance. The project was written and produced between Florida and Louisiana, reflecting on themes of love and loss against the backdrop of the deep American south. The release displays emotions of melancholy and ends with a cover of My Bloody Valentine’s “When You Sleep.” Pitchfork stated, “Suicideyear combines the clean melodic lines of late-1990s IDM with the slow-burn anxiety of Zaytoven.” Software Label re-issued Japan on vinyl and as a dual CD alongside Remembrance titled DREAM 727 in March 2015. The release included a cover of Britney Spears’ “Everytime.” A vocal version of his track "Scarr", featuring UK grime MC K9 was released following DREAM 727.
