I enjoyed this documentary/making of video of Black Sabbath looking back on their second album "Paranoid".
This serves as a terrific companion piece to the recent Deluxe Edition package, and has some of the alternative takes on display, as lovingly shown and remembered by engineer Tom Allom, who worked on the album - and indeed dropped the bombshell that he played the piano on Planet Caravan - (that bit's on the special features section).
Interviews with the four original members of Sabbath, engineer Tom Allom, ex-manager Jim Simpson and other luminaries such as Henry Rollins, talk about the band and their music and how this album became a legend.
It has footage - looks like old news reel footage of the Vietnam War, old atom bomb tests, and "duck and cover" propaganda with the music playing over it - adds a slightly surreal and much darker vibe to the music, as it shows exactly what they were writing about on songs like War Pigs, Electric Funeral and Hand of Doom.
The story of how this came to be is probably an old chestnut by now, but it's an album clearly still fondly remembered by all four members, and it also has footage of guitarist Tony Iommi, drummer Bill Ward and bassist Geezer Butler playing various parts of the songs at different intervals (though Ozzy doesn't sing, sadly).
Sometimes it's hard to believe that this album is now 40 years old, but that just shows the timeless quality of the music, and just how far ahead of their time Black Sabbath were, and how relevant they are today.
