Marta began singing in her native Krakow when she was still at school. She sang in a rock trio called Tino's Band.
She moved to Milan and began sending demos to various producers, exploiting her height (176 cm) and her Nordic looks to work as a model in the meantime. Although she enjoyed modelling, she never lost sight of her ambitions in the field of music.In 1993, Larry Pigagnoli spots her talent and, together with Davide Riva,the production team famous the world over for successful acts like Whigfield sets to work. The results are quick to arrive: "You Make Me Feel Good" goes to number one in Canada and performs well in France, Germany and Italy as well as other European countries. The second and third singles, "Beat It" and "You and I" perpetuate the J.K. success story.
