Released in 1969, Cloud Nine signalled The Temptations' power move into a psychedelic soul zone. With Norman Whitfield calling the shots from behind the boards, the title track sets the template of deep and funky grooves. Its centrepiece is the cautionary tale "Runaway Child, Running Wild", which finds the group embarking on an audacious, nine-minute musical journey that veers off into a freaky, hard-rocking jam session fueled by vicious organ riffs.
