50 years ago today (9/18/70) Black Sabbath released Paranoid, their second studio album. Paranoid features some of the band’s best-known signature songs, including the title track, ‘Iron Man’ and ‘War Pigs’. The album was originally titled “War Pigs” but allegedly the record company changed it to Paranoid, fearing backlash from supporters of the ongoing Vietnam War. The album remains a constant in the top five of the greatest metal album ever. Watch Black Sabbath perform the iconic riff fueled/drum filled “Fairies Wear Boots” off Paranoid live in 1970.
