It's a Blue World | The Four Freshmen / Mac Miller Cover

As part of our show Sounds of Steel: An A Cappella Tribute to Pittsburgh Artists, chapter quartet Chord Machine performs “It’s a Blue World,” the dreamy jazz ballad originally made famous by The Four Freshmen—and later reintroduced to a new generation by Pittsburgh’s own Mac Miller in his album Faces.

This performance blends vintage jazz harmonies with contemporary relevance, honoring both the song’s roots and its powerful return through Mac’s sampling. Featuring Dana, Evan, Khoi, and Stefan, Chord Machine delivers a haunting and heartfelt tribute to Pittsburgh’s deep musical soul.
