Karlo Metikoš, born in 1940 in Zagreb, was a notable Croatian musician known for his contributions to the music industry in the latter half of the 20th century. He gained recognition for his songs that entertained multiple generations in the former Yugoslavia and received a Porin award for his artistic work. Metikoš's music legacy is also intertwined with that of his wife, Josipa Lisac, who frequently mentions him during her concerts, highlighting his enduring impact on the music scene even years after his peak popularity.

Initially starting his career in dance halls in Zagreb, Metikoš faced challenges as a rebellious youth drawn to rock'n'roll, while the local market was predominantly inclined towards traditional pop singers. Although he briefly experimented with the popular music style of the time, he realized that it wasn't well-received by audiences who preferred more conventional entertainment forms. This revelation led him to seek opportunities outside Yugoslavia, ultimately shaping his identity as Matt Collins in Paris, a name under which he began to explore and develop his artistic potential fully.

Metikoš's transition to Paris marked a significant turning point in his career. In the vibrant cultural climate of the French capital, he immersed himself in the rock'n'roll scene, which resonated more with his artistic sensibilities. This shift not only allowed him to reconnect with his musical roots but also positioned him within a broader international context, where he contributed to the music scene dynamically and innovatively. His story serves as a testament to the transformative power of music and identity across different cultural landscapes.
