"My great friend Michael Cera not only is a brilliant actor, he also makes great music," Hill wrote.
The lo-fi album consists of 18 tracks, and features Cera on acoustic guitar. The songs have a folk music tinge, and include titles such as "Old Grey Whistle," "Sexy Danger" and "Smoke Eyes." The actor previously played bass guitar on tour for supergroup Mister Heavenly.
Cera is well-known for his role as George Michael Bluth on Fox/Netflix series Arrested Development, and as the title character of Scott Pilgrim vs. the World. He will next appear alongside John C. Reilly in Entertainment in 2015.
