When Pink Floyd Fought Ron Geesin Over 'Atom Heart Mother'

The collaboration on Atom Heart Mother started promising: Ron Geesin had worked with Roger Waters before and was brought in to turn a twenty-minute jam into an orchestral suite. But the studio sessions turned sour fast. Geesin later said the band would argue over every note, then walk out and leave him alone with the orchestra, only to return and demand changes that contradicted what he’d already written. He called it “a mess” and felt they treated him like a hired hand rather than a co-composer.

The tension was partly structural. Geesin had a background in avant-garde composition and wanted disciplined parts, while Floyd were still finding their studio identity—loose, drenched in tape loops and improvisation. They’d clash over tempo, dynamics, even the choir parts. By the end, the relationship was frayed enough that Geesin declined further work with them, though he did later provide string arrangements for a couple of Waters’ early solo tracks.

Did it feed future band tensions? Indirectly, maybe. The experience reinforced their distrust of outside arrangers. For years afterward, they handled strings and horns themselves or via trusted session players like Dick Parry. It also contributed to a growing sense within the band that Waters was becoming the de facto director—he was the one most engaged in the orchestration arguments, and Geesin noted that Waters took the lead in the creative shouting matches. The episode didn’t break the band, but it showed how easily a collaborative spirit could curdle.
