He is the younger half-brother of Roger Miret of Agnostic Front. The two have the same mother who is of Cuban descent and different fathers - hence the different last names. Freddy's father is from Colombia.
Freddy originally lived in Florida when his older half-brother Roger was living in New York and performing with Agnostic Front. Roger would write to Freddy telling him of touring and being in a band, and when Freddy was about 7 years old he began to ride along with AF on tour and ended up living in New York permanently. Roger and AF guitarist Vinnie Stigma took him under their wings and even let Freddy sing along with their cover of The Animals' "It's My Life". Around 1989 the idea came up to form a band with Freddy on vocals. Madball was originally formed as Freddy singing with the rest of Agnostic Front backing him up. Ball Of Destruction, Madball's first album, was a mishmash of older AF songs and other covers as well as unused songs. Soon after that came such albums as Droppin' Many Suckers, Set It Off and Demonstrating My Style, of which two are playing off the name of the DMS ("Doc Marten Skins") Crew, which Madball was a major part of. In July 2007, another album, Infiltrate The System, was released.
According to Freddy, he also works construction jobs, and has taken jobs at places like UPS. He is still seen as almost on par with his older brother as an icon and cornerstone of the New York hardcore scene.
Freddy occasionally does guest appearances on other bands' albums, for example Fear Factory (vocals on the bonus track Agnostic Front song Your Mistake), Deviate (vocals on Last Judgement), Sick Of It All (vocals on Forked Tongue on the Death to Tyrants album), H2O (guest vocals on the song 'Guilty By Association' on the F.T.T.W. album), 25 ta Life (guest vocals on 'Loyal To Da Grave' on the Strength Through Unity album), Shutdown (guest vocals on 'Few and Far Between' on the album of the same name), Skarhead (guest vocals on 'I Won't Change' on the album Kings at Crime, also on the song 'Skarhead' from an early compilation.
