Happy Birthday is a dizzying rush of nine songs, the album grew out of Wolfhard's personal challenge to pen 50 songs by the end of 2022. He admits, "I ended up writing a lot of terrible stuff, but a few of those songs I was really proud of went to the Aubreys. I started realizing a general theme in a lot of the other songs involving my identity, anxieties, nostalgia, childhood and loneliness. All of that was a part of a bigger puzzle. I knew I wanted to make a record, but I didn't know which songs." - For Wolfhard, who will be touring Happy Birthday this year, the album is another accomplished step forward in his evolution as a musician, songwriter and citizen of planet Earth. "If I were to walk away and listen to it in 10 years, I think it would feel like the beginning of a specific style and voice," he says. "It can be interesting being a younger person in any kind of industry, because even though I've been acting for a long time, I'm still only 22, and things start to take shape at different times in your life. I hope that when I look back on this record, I'll be proud of the melodies and the songwriting. I want to be accepting of myself at that time. It was okay that I felt like that and made a record about it and then moved on to new experiences."
