The BEMY team was founded by two brothers, Mattia and Elie Rosinski. They were born and brought up in France, but they have Polish origin through their parents. In the spring of 2015, they signed a contract with Universal Music Polska, where they released their debut album Grizzlin produced by Bogdan Kondracki, and already recorded in a full 4-member band. The album was well received by both fans and critics, which resulted in the nomination to Fryderyk in the category Debut of the Year. The album was also noticed abroad and even Ed Sheeran or LP joined in its promotion. Currently, the band BEMY is not only Mattia and Elie, but also the guitarist Wojtek Trusewicz and Konrad Załęski playing the bass guitar.
