“Yesterday” is track 9 on Atmosphere’s 2008 album, When Life Gives You Lemons, You Paint That Shit Gold.

Back in 2014, I spoke with Slug about what this song means.

“Somehow, the whole song was about me trying to make to make amends with my father who passed away,” Slug told me at the time. “Yet the premise was about when somebody dies, you feel like you see that familiarity of them and you feel like you recognize them in the faces of strangers. So it came from seeing people around my city saying, ‘Dude, that’s my dad.’ But really the song itself was about trying to make amends to the dead. I should have done that when he was alive. And I think that’s where, ultimately, no matter what you hear when you hear the song, it’s really about you as a listener. That song is there for a listener to pick up things for them, like, ‘I can totally relate because my mom passed away’ or ‘my brother’ or ‘my friend’ or some shit like that. Or you could just take it as being a song about making amends.”

In the song, which is open letter to his dad, Slug reminisces about their relationship while reflecting on regrets, love and everything in between. And if the last line doesn’t give you the chills, you didn’t listen to the song.
