Kwiinyanga zokuqala ze-2016, kulindeleke ukuqaliswa kwengqokelela yeengoma phantsi kwesihloko esithi "erlo”. Iya kuba licwecwe lakhe lesine lomsebenzi wakhe. "Erlo" isanda kufundiswa eLondon, phantsi kolawulo lukaJohn Davis (umvelisi wemisebenzi ye-REM, i-U2, phakathi kwabanye).
I-Grises yibhendi edlala into ebizwa ngokuba "Electropop". Bavuka kwidolophu yaseGipuzkoan yaseZestoa, ngenxa yeqela langaphambili elibizwa ngokuba yiGrey Dreams. Olunye utshintsho kuyilo lokuqala kunye nokuchazwa ngokutsha kwesitayile sabo, lunike ubume kunye negama kwinto abayiyo namhlanje.
Phakathi kwamaqela aseSpeyin angena kwindawo yomculo ngeli xesha, iGrises yenze njalo ngamandla kunye nokwamkelwa okuhle kakhulu. Licwecwe lokuqala, elanikezelwa ngo-2011 phantsi kwegama elithi "The Ballpoint Man", laliquka ingoma ethi, "Parfait", eyaba yimpumelelo ngokupheleleyo kubaphulaphuli. Emva koko kuya kubakho ezinye izihloko eziye zaziwa kakuhle, ezinje ngokuba “isilwanyana", ngo-2014.
Icwecwe ebebelidlala kulo nyaka ka-2015, “Isilwanyana”, sesona sivuthiweyo kwaye siphuhlileyo kumsebenzi wabo omfutshane kodwa othembisayo. Isandi sokwenyani esinamalungiselelo ambalwa, anee-nuances kunye neempembelelo ezivela kwi-Alglo-Saxon, ukusuka kwizitayile ezifana ne-synth, i-power pop kunye ne-post punt. Isimbo seGreys kuthi khumbula umculo we-elektroniki ukusuka kwi-80s, idityaniswe nemimoya entsha, kunye ne isiginci esinamandla kwaye iyasebenza ngaphambili. Abo bebezimase imiboniso yabo ephilayo bathi iyamangalisa.
"Isilwanyana" sivumele ibhendi ukuba idibanise kwindawo yomculo. Iingoma ezifana ne "Odd", "Mork", "Indecision" kunye nesandi sayo esithi "Wendy", kunye ne-airs of fiction kwi "Lopan". Iingoma zicingisiswe kwaye zinomyalezo.
