Adam McIlwee (born March 11, 1989), better known by his stage name Wicca Phase Springs Eternal, is a singer-songwriter and producer from Scranton, Pennsylvania. He is a member of emo-rap collective GOTHBOICLIQUE, super-group Misery Club, duo Coward and band Pay For Pain. He is also a former member of emo-band Tigers Jaw and rap collective Thraxxhouse.

McIlwee started playing guitar at 13 and around that time he founded his first band, Closed Mouth.
During his middle school years, he played in different punk and ska bands (Green Chair, Bad Seed, and Captain, We’re Sinking, among others) along his friend Ben Walsh, but they were always kicked out.

In 2005 Adam and Ben formed emo band Tigers Jaw, which he left in 2013 to pursue a solo project. Wicca Phase Springs Eternal originally started as an electronic project, but once he started getting beats from producers he switched to emo/cloud-rap music.

His stage name Wicca Phase Springs Eternal was suggested him by visual artist Caroline Bren he knew on Tumblr. He emailed her “what do I call this project?”, and she just said “Wicca Phase Springs Eternal.” According to a Reddit user, the name has roots in the phrase “Hope springs eternal [in the human beast,]” which essentially means that hope is forever-lasting. When we replace “Hope” with “Wicca phase”, it can be interpreted to mean that the wicca phase in one’s life is forever-lasting.

Wicca is a pre-christian religion that in simple terms is focused on the supernatural and black magic. Followers of this religion emphasize ritual observance of seasonal and life cycles, hence “springs eternal”.

Some of his musical influences are Phil Elverum, Bright Eyes, Bob Dylan, Lil B, Clams Casino, and Bonnie “Prince” Billy.
