With their highly anticipated collaborative album coming soon, Saga and Thelonious Martin drop their gripping and lyrically rich lead single, “Yesterday,” featuring a compelling guest verse from Fashawn.

Musically, you have Martin showcasing his production wizardry by combining slapping percussion with a crazy sample flip. It’s really yet another example of why the Chicago producer is one of the best doing it right now.

And the same goes for Saga, the Brooklyn-based rapper whose career continues to blossom. With that in mind, there’s extra potency to his rhymes on “Yesterday,” a track that dives deep into growth—both as an artist and as a man.

Whereas Saga digs into the former with his book-ending verses, Fashawn passionately raps about being a young father who finds truth and power in his role as a parent.
