Somebody at Warner must've felt the band's glory days were over after they'd released Sabotage and that it called for a compilation of the "classic" era (1970-'76). Up to that point, the band hadn't released one single album that was less than satisfying (really!), but all of them, including their peak Paranoid, contained questionable and even bad stuff, so it's no surprise this compilation isn't the most consistent one on the market. The inclusion of weaker material is no problem in itself, but it does become one when it's at the expense of quality material. It's understandable that four songs were picked from the first two albums (and all four songs from the second album are simply fantastic), and I even won't nag about the inclusion of a mere two songs from sludgefeast Master of Reality, but why the hell would you include "Changes" and the mediocre "Tomorrow's Dream" when there's also "Supernaut" on Vol. 4? Since only its title-track is included here, Sabbath Bloody Sabbath is under-represented (the accessible "Killing Yourself to Live" would have been great), but the compilation's main flaw arrives when you realise what they picked from Sabotage.... Only "AM I GOING INSANE (RADIO)"!!! I mean... what's up, man? That album - tacky though it may be - includes "Hole in the Sky" and "Symptom of the Universe," definitive Sabbath songs that even should've been here if it had been a 10 song-compilation. So yeah, they sold their soul for rock 'n' roll. And a few pansy blunders like "Changes" and that radio song.
