Isaac Hayes' 1971 soundtrack album flipped the script on film music — a sprawling, erotic, streetwise symphony of wah-wah guitars, string sections, and monologues that made blaxploitation sound like truth. Essential for anyone who wants to hear where funk and soul peaked in the early seventies.
The first time the wah-wah guitar comes in on “Theme from Shaft,” you don’t just hear it. You feel it right where your ribs separate.
Isaac Hayes had already been writing hits for Stax for years when he got the call to score Gordon Parks’ film. He was the house songwriter, the guy who could turn out a Sam & Dave single before lunch. But Shaft let him build something whole. He brought in the Bar-Kays on rhythm — those cats had lived through the plane crash that killed Otis Redding and came back meaner. He wrote string parts that owed more to Ravel than to Berry Gordy. And he kept his own voice low, almost a whisper, until the word “Shut your mouth” hits and you remember why people talk about this record like it’s a holy text.
The sessions happened at Stax Studios in Memphis, 1971. Ron Capone engineered the whole thing with a tape machine that probably should have been retired five years earlier. They cut the rhythm section live in the room, which is why the snare sounds like someone hitting a concrete block with a leather glove. Hayes overdubbed the vocals and keyboards later, and he kept the arrangement spare where it mattered — listen to how little happens under his spoken intro, just a hi-hat and a bass note holding the floor.
“Ellis in Chains” is the deep cut that proves Hayes could do more than funk. It’s a slow, string-swollen thing that sounds like a score for a sex scene that got cut for being too honest. The oboe line near the three-minute mark is pure anguish, and that wasn’t on the chart — the player just found it during the take, and Hayes left it in. Those moments are all over this album: accidents that became signatures.
People forget that Shaft isn’t just the theme song. Side two opens with “Do Your Thing,” a nineteen-minute jam that takes up the entire second half of the original vinyl. The Bar-Kays lock into a two-chord vamp and Hayes rides it like a long-distance truck driver. He laughs on the mic. He talks to the musicians by name. He tells a woman in the control room to “say something, baby.” It’s not a song. It’s a document of a room full of people who knew they were making something that would outlive them.
The sound of the record is what keeps me coming back. The kick drum is so low and round you feel it in the back of your throat. The strings are recorded with a slight saturation, the kind you get when you push a console until the transformers start to sag. The stereo spread is wide and deliberate — Hayes wanted the listener to sit between the horns and the rhythm section, right there in the room with him.
And then there’s the monologue. “Cafe Regio’s” opens with Hayes speaking over a single bass note, describing a woman in a restaurant. He doesn’t sing for nearly two minutes. He just paints a picture with his voice, low and slow, the same tone he used when he was a kid reading the Bible to his grandmother. That’s the genius of this album. It doesn’t just score a film. It teaches you how to listen.
The album won the Academy Award for Best Original Song, making Hayes the first Black composer to win that category. He accepted it in a gold-trimmed tuxedo and said nothing about the symbolism. He didn’t need to.
What you hear when you put this record on now is the sound of a man who had absolute authority over his own voice, his own band, and his own moment. He never rushed. He never pandered. He just let the wah-wah guitar ring out until the movie started.

Why is the 'Shaft' soundtrack considered such an important album?
It broke the mold for film scores by treating them as fully developed soul albums rather than background music. Hayes' use of spoken monologues, orchestral arrangements, and extended jams influenced every blaxploitation soundtrack that followed and earned him an Oscar.
What instruments are prominently featured on the Shaft soundtrack?
The album is built around a wah-wah guitar (played by Michael Toles), a tight rhythm section of bass and drums, and layered strings and horns arranged by Hayes himself. Hayes' own electric piano and deep baritone vocals are the anchor.
Is the entire album instrumental or are there vocals?
Most tracks feature Hayes' vocals, often in the form of spoken monologues (like 'Cafe Regio's') or full singing. Two tracks are purely instrumental: 'Bumpy's Lament' and 'Ellis in Chains,' though the latter includes wordless vocal cries.
