It was sold at Barenaked Ladies concerts in late 2003, but wasn't officially released until 2004.

Night Light is a more upbeat album than the band's previous release, H-Wing, which was written largely while Hearn was in the hospital receiving treatment for leukemia.

By the time he began to write and record Night Light, the disease was in remission.

References to the disease are still present (from "Jocelyn": I decided in my head/That I would come back from the dead), but songs like the title track, "Ball of Twine" and "Born Human" are more upbeat than Hearn's previous album, both in tempo and in message.

In addition to providing lead vocals and playing guitar, accordion, piano and keyboards, Kevin Hearn drew the album cover.
