The Petreuș brothers (Ștefan and Ion) sing traditional music from the Romanian region of Maramureș.
They were noted for the numerous instrumental and vocal recordings they made and for the discographic materials they developed. They made their radio and television debut in 1968, and recorded their first album in 1969-1970.
In 1966, Ștefan Petreuș joined the folk music orchestra of the “Maramureșul” Ensemble from Baia Mare. The following year, his brother Ion also joined the orchestra.
