All Along the Watchtower was written by Bob Dylan and released on his 1967 album John Wesley Harding, before Jimi Hendrix recorded the definitive electric version in 1968 for Electric Ladyland. Hendrix's arrangement became so iconic that Dylan later adopted it in live performances. The song has since appeared in films, television and countless covers, which keeps its opening instantly familiar across generations. Online, like hello darkness my old friend, it has become shorthand for a grave, cinematic mood that creators borrow for edits, tributes and dramatic montages.
