Oni Logan is a hard rock vocalist. He was born Leonardo Onito Agustus Jimenez in Argentina and raised in the United States (New York, Connecticut, and Florida). He is perhaps best recognized as the original (and, once again, current) lead singer of the band Lynch Mob.\r \r He first played in the band Diamond Rose in South Florida from 1985 to 1987. That band consisted of Dave Rhodes (guitar), Mike D'Amico (drums), Marc Wolpert (bass), and Mark "Smitty" Smith (guitar). The band was well known in South Florida, but Oni left the band and went to L.A. early in his career to become a member of the band Ferrari. Shortly after that, he became the original lead singer for the band Lynch Mob, featuring lead guitarist George Lynch, who had recently left the band Dokken.
