Black Sabbath put “Changes” and “Supernaut” on the same side of Vol. 4, separated by the echoing noises of “FX.” A piano ballad, a studio experiment, and a riff that gives Bill Ward almost as much to do as Tony Iommi: plenty can happen before you turn the record over. What holds Vol. 4 together when the songs pull this far apart?
Released on September 25, 1972, the album was recorded at Los Angeles’ Record Plant by Iommi, Ward, Geezer Butler, and Ozzy Osbourne. Sabbath had moved on from producer Rodger Bain, and now the band and manager Patrick Meehan shared the production credit. That change gave them room to pursue arrangements that could stretch well beyond a riff and a vocal.
The opening “Wheels of Confusion” establishes how much can happen inside one song. Iommi’s bluesy opening lead gives way to a thick, dragging figure, but Ward refuses to treat it as a reason to sit still. His fills spill around the guitar while Butler’s bass adds movement underneath. Ozzy draws out the words about childhood certainty giving way to disappointment. Even after he finishes, the song has another section to explore: “The Straightener,” where a repeating backing figure supports layers of lead guitar.
That relationship between repetition and movement matters across the album. “Supernaut” has a riff you can recognise within seconds, jumping from low notes into a higher, curling phrase. Ward keeps changing what happens around it. His accents and fills give the guitar a bounce, and the percussion break develops a rhythmic idea already present in the song. When Iommi comes back in, you hear how much of that riff’s character comes from the drummer.
The quieter material makes a different connection clear. Iommi’s repeating piano chords in “Changes” are as central to its arrangement as his guitar figure is to “Supernaut.” Sustained Mellotron fills the background, leaving Ozzy to supply most of the variation. He stretches the melody over those steady chords, his thin, strained tone suiting the regret in the lyric. With no drums or distorted guitar around him, you can hear how much Sabbath depends on the particular sound of his voice.
That voice also helps explain why “Snowblind” can accommodate both a lurching riff and gentler passages without sounding pieced together. Ozzy’s delivery remains eager as the cocaine imagery turns cold and isolating. The lyric describes dependence from inside the experience, where pleasure still makes the consequences easy to dismiss. Strings broaden the arrangement, but the repeated guitar figure keeps drawing the song back to the same place. Its musical appeal and lyrical unease are difficult to separate.
The recording doesn’t smooth everything into a consistent finish. Guitar and bass can crowd together during the louder passages; the piano and acoustic arrangements leave individual notes much more exposed. “Laguna Sunrise” gives Iommi’s acoustic playing space against an orchestral backing, while “FX” briefly abandons melody for echoing sounds. Some of these departures develop into complete compositions. Others remain short experiments. Their inclusion makes the album less predictable without requiring every song to become longer or more complicated.
Vol. 4 holds together because Sabbath keeps using repetition to give those different arrangements a clear shape. You can follow the piano pattern in “Changes,” the guitar beneath “The Straightener,” or the returning riff in “Snowblind” while the musicians alter what happens around it. “Under the Sun” brings that approach back to the full band, moving from its crawling introduction through quicker passages and into an extended guitar ending. The ballad and acoustic instrumental haven’t interrupted the album’s logic. They’ve made it easier to hear what Sabbath can do with a simple figure once they give it time.
