Narrative:

While on a visual approach to atl; we encountered wake turbulence. The aircraft began to roll right and went to 30 degrees bank and then began to pitch down. At that point; I disconnected the autopilot and auto-throttles and performed the nose down unusual attitude maneuver. The bank of the aircraft approached 40 degrees and the bank angle announced once. Pitch attitude was almost five degrees down. Once the aircraft was stable; I continued the approach uneventfully. The aircraft ahead of us was aircraft Y which was on a similar flight path. Preceding that aircraft was aircraft Z. Aircraft Y had arrived on the downwind leg to the airport and had requested a lower altitude while on base leg. I believe it was the aircraft Y's wake turbulence we encountered.
