Addendum: Recovery log 16/01/20██
SCP-XXXX came into attention of the Foundation after destroying several buildings in ██████, a district of █████████, Germany. It was found wearing █████ brand headphones and crying in the ruins of the buildings it had destroyed. Later examination of the mp3-player connected to the headphones showed it had been listening to the album ███ ██████ ████████ by █████████ ██████████, which contains 11 aggressive and one sad song. Neither the headphones nor the mp3-player were found to be anomalous.
Addendum: Incident report 19/04/20██
SCP-XXXX was asked to compose music in its head the prior day for testing purposes. At 0716 a patrolling facility guard heard a punching sound against the door of its cell. Upon opening the cell door, he saw SCP-XXXX standing in front of the door and stomping on the floor in a rhythmic manner. The facility guard asked what he was doing, to which SCP-XXXX responded "Do you feel the beat?" and knocked the facility guard uncocious. It then tried to escpape the facility, destroying several reinforced doors in the process. It was successfully recontained by tranquilizing it.
A reaction to this incident new containment procedures were put in place.
