He has been the singer and main composer of Almafuerte since 1995.
His songs are realistic urban stories dealing with the life of lower classes, as well as Argentine 'metalheads'.
Even though he played the bass with every band he integrated, he has recently chosen Beto Ceriotti to be the new bassist of Almafuerte, remaining as the singer and main composer of the band (mostly lyrics).
Extremely nationalist, Iorio continuously proclaims in his songs and in the media the pride in being Argentine and Argentine history, and mixes native music styles like tango, Indian and gaucho culture with the heavy metal base of Almafuerte.
The young people who go to Almafuerte's shows consider him to be like a patriotic guru.
He left Buenos Aires city to live in the countryside, where the pampa starts to turn into Patagonia, with his daughter SofÃa and his girlfriend Fernanda.
He also had a great friendship with the late argentinian guitar player Norberto Napolitano, also known as Pappo, who invited Iorio to record some songs for his "Pappo y Amigos" album.
