Frank Anthony Iero, Jr. (/aɪˈɛ.roʊ/, born October 31, 1981) is an American musician who is the rhythm guitarist and backup vocalist of the rock band My Chemical Romance and post-hardcore band Leathermouth. He has a solo project titled Frank Iero and the Future Violents (formerly frnkiero andthe cellabration and Frank Iero and the Patience). He released his debut solo album titled Stomachaches on August 26, 2014.
He was born in Belleville, New Jersey. As a child, he suffered numerous bouts of bronchitis and ear infections, which meant he spent a lot of his childhood in the hospital. Frank is also lactose intolerant and has other various food allergies. He attended a Catholic school as a child. He went to Rutgers University on a scholarship, but dropped out to go on tour with My Chemical Romance.
Iero's parents split when he was young and he grew up living with his mother, who lent out her basement to her son's many band practices; his father and grandfather were musicians and both were big influences on Iero when he was young. His father urged him to play drums, but Iero later began playing the guitar.
