Starting on Eb2, listen to the shift at Cb2 to subharmonics down to Eb1.

Subharmonics – rediscovering and redefining undertone, strohbass, and vocal fry. For over five years now, I have dedicated my time to learning and developing this part of my voice as a viable technique and I have only had the greatest success within the last year. Subharmonic singing has piqued my interest since I started singing in college years ago. Because there is little research done on this subject, I will be extra cautious in approach, fatigue, and long-term effects.
