Fifty year ago today the song that would change (nearly) everything was released--Dylan's first electric single, "Subterranean Homesick Blues." Not a giant hit but every single rocker and folkie was listening (including Bob). Also, you might say, the first "rap" single. Also sparked what some call the first true "music video" precursor, the opening of D.A. Pennebaker's "Don't Look Back" doc. Bob was turning rather "apolitical" then but the song lyric even lent the name for the radical group The Weathermen.
