The album is a real sign of the times with politically charged lyrics dealing with the injustice of the Vietnam war. The album was seen as pretty controversial, but was also really loved by critics such as Rolling Stone.
Technologically, the album was actually ahead of its time with the usage of the state-of-the-art 16-track tape machine giving the album its powerful layered sound. Sonically and historically this album still has music fans interested after 55 years, making it a real classic.
