Berni Gruber has two passions: Nordic Combined and rock music. Before he decided to commit himself to pursuing an athletic carreer and attending the Ski Gymnasium in Stams, Austria, he even went to a music school. Although Gruber has been a fixture in the Nordic Combined World Cup since 1998, he always finds time and opportunity to make music another part of his life, too.

Together with his Nordic Combined fellow athletes Tino Edelmann, Ronny Heer and Christoph Menz, guitar player Gruber founded a band called the "Telemarkers" in 2009 and recorded a song called "Für den einen Moment" ("For that one moment") which was meant as an anthem for the sport of Nordic Combined.

Being used to the spotlight as a musician is one side of open and friendly Berni Gruber but having a rockstar attitude definitely does not belong to his nature. He is modest when it comes to his position in the team: "I don't think that I'm team leader of the Austrian team. I think I can still learn a lot from my experienced teammates like Mario Stecher. The most important thing is that it's a lot of fun to work with the team and compete."
