Ko te whakaaturanga ora tuatahi o te roopu i tu i te Oketopa 17, 1987, i Rod's Hickory Pit i Vallejo, California. I te tau 1988, ka tiimata a Armstrong me Dirnt ki te mahi tahi me te kaiwhakaari o Isocracy o mua a John Kiffmeyer, e mohiotia ana ko "Al Sobrante". E kii ana a Armstrong i te roopu Operation Ivy (i whakaatuhia a Tim Armstrong me Matt Freeman o Rancid) hei mana nui, me tetahi roopu i whakaaweawe i a ia ki te whakatuu roopu.I te 1988, ko Larry Livermore, rangatira o Lookout! Records, i kite i te kapa e whakatangitangi ana i te tīmatanga o te whakaaturanga, ā, i hainatia e ia te rōpū ki tana tapanga. I te tau 1989, i tuhi te roopu i tana whakaaturanga tuatahi, 1,000 Hours. I mua i te 1,000 Hours i tukuna, i whakarerea e te roopu te ingoa Sweet Children; e ai ki a Livermore, i mahia tenei kia kore ai e pohehe ki tetahi atu roopu a rohe Sweet Baby. I tangohia e te roopu te ingoa Green Day, na te hiahia o nga mema ki te tarukino. I tukuna e Lookokout! te pukaemi tuatahi a Green Day, 39 / Smooth i te timatanga o te 1990. I tuhihia e Green Day nga taakaro roa e rua i muri mai i taua tau, Slappy me Sweet Children, ko te mea whakamutunga ko nga waiata tawhito i tuhia e te roopu mo te tapanga tuhi motuhake a Minneapolis Skene! Ngā pūkete. I te tau 1991, Ko te Matakitaki! I tukuna ano e nga Kaiwhakahaere 39 / Smooth i raro i te ingoa 1,039/Smoothed Out Slappy Hours, me te taapiri i nga waiata mai i nga EP tuatahi e rua o te roopu, Slappy, me te 1,000 Hours. I te mutunga o te tau 1990, i muri tata mai i te haerenga tuatahi a te roopu puta noa i te motu, ka wehe atu a Kiffmeyer i te rohe o East Bay ki te haere ki te Whare Wananga o Humboldt State i Arcata, California. Ko te kaiwhakatangi o te Lookouts a Tré Cool i tiimata ki te whakakii hei whakakapi mo te wa poto, ana i muri mai ko te tuunga o Cool hei kaiwhakatangi o Green Day ka noho pumau, na Kiffmeyer "i whakaae". I haere te roopu ki te haerenga mo te nuinga o te tau 1992 me te 1993, a he maha nga whakaaturanga i puta i tawahi i Uropi. Ko te pukaemi tuarua a te roopu Kerplunk i hokona 50,000 kape i te US.  Pātai: Ko tēhea ngā waiata e rua anō i whakaurua ki te whakaputanga anō o te 39/Smooth?
Ko Slappy, me ngā haora 1,000
