Cory Brennan and his Five B management team previously had legendary metal outfit Megadeth as a client. The relationship went south at some point, and Brennan ended up suing Mustaine for refusing to pay him.
Lawyers for Brennan said (as reported by Billboard): “Dave Mustaine, who has a known history of firing advisors, terminated Five B Artist Management after 9 years of their having resurrected his failing career. Ignoring the success Five B had helped Dave achieve, including a campaign to help him win his first Grammy, the release of two hit albums, and the elevation of his touring from small clubs back to arenas and amphitheaters, Dave simply refused to pay commissions owing and forced 5B to file a lawsuit.”
Brennan and Five B ended up being successful in the lawsuit to the tune of $1.4 million. Mustaine’s lawyers argued that there was a previous agreement in place that each party would “go their separate ways” following a split. Mustaine claimed that his Brennan-led career was “plagued with missteps,” and that it “dealt serious blows to Megadeth’s reputation.”
Mustaine’s claims against Brennan unrelated to the commission settlement, which include breach of contract and negligence, were not resolved and litigation will continue.
