Narrative: While descending through approximately 20;000 feet on the arrival we encountered a compressor stall with self recovery on engine number 1 (heard loud popping; aircraft experienced slight yaw moment).  All engine parameters indicated normal. PM (Pilot Monitoring) briefed the Flight Attendants and made a PA to the passengers explaining what happened.  Approximately 3 minutes later we had an indication of N2 overspeed (~103%). PF (Pilot Flying) reduced thrust on the engine to bring it within normal limits which was immediately followed by a ENG 1 FUEL CNTRL FAULT. FO (First Officer) continued to fly the airplane while CA (Captain) was completing the ECAM procedure. The ECAM procedure directed the ENG 1 to be shut down. PF notified ATC and requested vectors to final approach for Runway XXL. PM completed the ECAM procedure and the QRH follow up for the ENG FAIL. PM briefed the Flight Attendants on a Precautionary Landing according to the Non Routine Landing Considerations. PM conducted a PA to the passengers to explain the situation and to expect ARFF (Aircraft Rescue & Fire Fighting) to check the airplane on the outside. We were cleared for a visual approach to Runway XXL which we backed up with the ILS. PF conducted a normal approach and landing and stopped the aircraft on the runway short of Taxiway D.  PM requested that the Fire Commander check the outside of the aircraft for any damage or leaks. After ARFF inspected the aircraft and reported no signs of damage or leaks we taxied to the gate.  After arriving at the gate; we called Dispatch to notify them of the precautionary landing.  Dispatch patched us through to Maintenance Control.  We discussed the ECAM / engine indications with Maintenance to aid in the log discrepancy write up.


Second narrative: While descending through approximately  20;000 Feet we encountered a compressor stall with Self Recovery on engine number 1.  All engine parameters indicated normal. I briefed the Flight Attendants and made a PA to the passengers explaining what happened. A Captain sitting in the cabin reported a big flash on the left side of the aircraft. Approximately 3 minutes later we had an indication of N2 overspeed (~103%). Reduced thrust on the engine to bring it within normal limits which was immediately followed by an ENG 1 FUEL CNTRL FAULT.  FO (First Officer) continued to fly the airplane while I was completing the ECAM procedure. The ECAM procedure directed the ENG 1 to be shut down. We requested priority handling and vectors to final approach for RWY XXL. Completed the ECAM procedure and the QRH follow up for the ENG FAIL. Briefed the Flight Attendants on a Precautionary Landing according to the Non Routine Landing Considerations. Conducted a PA to the passengers to explain the situation and to expect ARFF (Aircraft Rescue and Fire Fighting) to check the airplane on the outside. We were cleared for a visual approach to RWY XX L which we backed up with the ILS. FO conducted a normal approach and landing and stopped the aircraft on the Runway near taxiway D.  Communicated to the Fire Commander to check the outside of the aircraft for any damage or leaks. After ARFF inspected the aircraft and reported no signs of damage or leaks we taxied to the Gate.  After arriving at the gate; we called dispatch to notify them of the precautionary landing.  Dispatch patched us through to Maintenance.  We discussed the ECAM / engine indications with Maintenance to aid in the Log discrepancy write up.
