Time Has Come Today

"Time Has Come Today" by the Chambers Brothers, has been described as psychedelic rock, acid rock, and psychedelic soul.  Whichever you prefer, the song is recognized as a landmark of the psychedelic era. In 1967 the song climbed to #11 on the Hot 100, but stayed there five weeks, and on the charts for that many months.  Today it's mostly a forgotten oldie.
