There is limited widely documented information under the name "Mille, ozzy" as a distinct musical artist or band in major public music references. If this refers to Mille Petrozza, the German vocalist and guitarist of the thrash metal band Kreator, or to Ozzy Osbourne, the English singer known for his work with Black Sabbath and as a solo artist, those are separately well-known figures: Mille Petrozza is associated with German thrash metal from the 1980s onward, and Ozzy Osbourne is associated with pioneering heavy metal from the late 1960s and his solo career from the 1970s. No clear, reliable sources identify "Mille, ozzy" as an established joint project or single act under that exact name.
