This song I downloaded from a file sharing application in the early 2000s. I've been searching for the artist for about two decades, nothing (the forum posts that come up when you search for it are also me).
It sounds like Christian music to me. Idk if that's true but growing up in that religion I get that vibe from the song. Might be worthwhile to try to find some small time bands from around the years you initially found it. Good luck on your search.
It was originally labeled as Jars of Clay, and it certainly fits the genre, but the lead singer isn't the same. There were a ton of smaller bands from those years with pretty much the exact same sound, I never managed to find a match.
At this point, I'm guessing it was an unreleased demo or something. In which case, unless the original artist finds it, I doubt we'll ever know.
