The band released their EP Pure Sun (새삼스레 들이켜본 무중력 사슴의 다섯 가지 시각) in August 2015.[2] They signed with the label after sending their demo to BGBG Records, and began recording their first studio album.[3]
Kang Minjeong of IZM reviewed "Silica Gel is extremely present, fierce. The birth of a band full of "youth.""[4] The member of the selection committee for the Korean Music Awards Choi Jiho described the album as "The land they are stepping on is the world of plastic lyricism of synth-pop in the 80s and capitalist freaks created by post-punk. It is deeply rooted in the tradition of the genre. Somewhere between this tradition and the tension of injustice, this album exists," and the band won Rookie of the Year.[5]
