After Dark was originally released by American artist Mr. Kitty on the 2014 album Time, where its dark synthpop sound built a cult following online. Years later the track found a second life in fan edits on TikTok and YouTube, with pitched and sped up versions becoming especially popular for their brighter, more intense feel. Short excerpts are now shared as ready made audio for edits and montages, helping the song stay recognisable even to listeners who have never heard the full original recording.
