Born in Premià de Mar, Marta Riera (1996), better known as DJ Trapella, became interested in selecting music as a child: "I was in charge of preparing the CDs for family car trips." She was interested in music and during her adolescence she saw "very clearly that I wanted to be a rock star," but she wasn't quite sure how. "When I was 18, I went into a nightclub for the first time and saw the DJs juggling with live music. And I said: that's it," she explains.Companies.
