Observant Records is the exclusive label for Eponymous 4 and Empty Ensemble.

Eponymous 4 is a play on Anonymous IV, an unnamed English student whose writings are some of the few existing documents regarding French music from the Middle Ages. Eponymous 4 is also the home studio project of Greg Bueno, a web developer and lapsed musician.

Empty Ensemble is a play on the term "empty orchestra", or "karaoke" as it's more famously known. Empty Ensemble is a spin-off of Eponymous 4 focusing on works of a more classical music nature.
