Baltimore-based quartet Horse Lords consists of Andrew Bernstein, Max Eilbacher, Owen Gardner, and Sam Haberman. The track “May Brigade” off their latest album, Comradely Objects (2022), was included on Pitchfork’s list of the best songs of the year.

The band incorporated “third-ear” psychoacoustic effects for “Untitled (Ear),” structuring the driving instrumental around the Fibonacci sequence, a fractal pattern that approximately describes the shape of the outer ear.
