He started experimenting with music. at a young age. He found Hector rapping in the bleachers of a park when he was 14-year-old he joined him rhythming. They started singing around in Puerto Rico parties, hanging out and, the lyrics were about what was trending back then on the island. It began as a hobby to him and, he ended quitting to then start on the streets. He eventually realized that his talent would give him more money than the 'street business'.
Along with Hector "El Father and Rey 29, as a teenager, he formed Masters of Funk, a rap group that never recorded any albums but one, that helped plant the seeds for the impending reggaeton movement. When the trio split, Voltio partnered with Karel, and the duo billed itself as Karel y Voltio, appearing on some stray compilation albums and garnering label interest in the process.
Los Dueños del Estilo made their album debut in 2003 when New Records released Los Dueños del Estilo. The album drooped, however, and the duo's enthusiasm dwindled. Elías de León -- the owner and founder of White Lion Records, the home of Tego Calderón -- liked what he heard, regardless of the album's poor performance, and he presciently offered Voltio a solo contract. The resulting album, Voltage/AC, was quite a breakthrough, spawning a big club hit ("Bumper") and "Julito Maraña," a popular song for which White Lion released an extended-form DVD video.
In late 2005 Voltio returned with his next album, a self-titled release issued by White Lion in partnership with Sony Norte. While Voltio combined a few songs that had appeared on Voltage/AC, including the aforementioned "Bumper" and "Julito Maraña," it did feature mostly new songs, "Chulin Culin Chunfly" standing out among them. The album elevated Voltio's profile noticeably, ranking him up there among reggaeton's leading voices in terms of influence as well as fame.
The iconic puerto rican also featured on a remix of the song "Locked Up" by Akon, which was released in the UK as part of Locked Up-Global Remixes.
Voltio recently teamed up with Calle 13 to speak out against police brutality in Puerto Rico. On August 11, 2008, announced the publication of a documentary titled "En vivo desde Oso Blanco". The production covers the time that Voltio spent in prison. Today, Julio Voltio is defined as a born-again Christian, this 42-year old Puerto Rican went from having a longtime feud with Hector El Father, to now co-hosting a Christian radio show with his past rival, Hector Delgado (Hector "El Father").
