Eric Prydz picked an odd moment to look forward. On September 1, the Swedish producer left a comment under a birthday post from Mark Gillespie, the founder and CEO of Three Six Zero: "Oh wow. Didn't know. Happy birthday! My new MANAGER!! I'll do better next year." That one line confirmed what industry watchers hadn't yet clocked: Eric Prydz has moved his management to the same company that built Calvin Harris, Tiesto and Swedish House Mafia into global touring businesses.
On paper it's a routine upgrade, a veteran producer joining a bigger roster with more Hollywood-adjacent muscle. But the timing lands right on top of a much uglier story that has nothing to do with music and everything to do with money.
What is Prydz actually suing over?
Less than a year before the Three Six Zero news, Prydz filed a lawsuit in California state court, on October 28, 2025 per Music Business Worldwide, against Thomas St. John, the business manager who had handled his taxes, financial record-keeping and touring finances since around 2012. The complaint seeks $269,000 in damages plus punitive costs, built on three specific allegations: $219,000 paid out for services Prydz says he never authorized after a 2023 contract renewal, a $150,000 demand for "unapproved, out of scope" work that St. John allegedly required before he would file Prydz's overdue tax documents, and a $50,000 withdrawal Prydz says happened without permission after the contract was already terminated.
The language in the filing is blunt. "Instead, he is a fraud who not only abuses the trust of his clients, he takes money from them without their knowledge or authorization for his personal use and benefit," the complaint reads, according to Music Business Worldwide.
"He is a fraud who not only abuses the trust of his clients, he takes money from them without their knowledge or authorization for his personal use and benefit."
Why does the Calvin Harris connection matter here?
Because Prydz isn't the only star accusing Thomas St. John of the same thing, just at a very different scale. Calvin Harris separately filed an arbitration demand against St. John alleging he lost $22.5 million through CMNTY Culture, a Hollywood real-estate project St. John steered him into. Harris says he put in $12.5 million and loaned another $10 million, and has seen zero return since 2023. St. John has denied wrongdoing in both cases, saying that not a single dollar has been misappropriated.
Two of dance music's biggest touring names, managed by the same Hollywood business manager, both now alleging he used their money without authorization. That's not a coincidence the scene can shrug off: it's exactly the kind of story that makes artists and their teams ask who else is signing off on their behalf, and how closely anyone is actually watching.
What does this mean for the rest of the industry?
Business managers sit quietly behind almost every major touring artist, handling the money nobody on the timeline ever sees. When two clients of the same manager independently accuse him of taking funds without approval, it's a signal for every artist paying someone else to sign their checks to ask harder questions about oversight, not just trust a long relationship on its track record.
