Hardy described the title track from his debut album, A Rock
, as a "stoner idea" about how rocks are significant throughout our lives - from skipping rocks in a pond at the beginning to being buried beneath a tombstone at the end. In a 2020 Songfacts interview
, Hardy explained how he came up with the idea:
"I was just driving down the road and was thinking about all the ways that a rock is important, like how a tombstone is made from a rock, and the roads you drive on a lot of times are made out of tons of rock, and engagement rings are made of rock, and when you think about it, iron comes from a rock, and if there wasn't iron, there wouldn't be pretty much any metal. I know that sounds ridiculous, but then I just wrote down 'A Rock' in my phone because I just was like, 'That's a weird idea.'"
