XV is a particularly important project for the artist. Her greatest hits were sung by her once again and rearranged by young producers. In them, he presents the duality of human nature. Two different worlds, extreme emotions, good and evil.

The artist juxtaposes an electric, turbulent, dark and predatory universe of sounds with a sensitive, melancholic, sublime one, balancing on the verge of sacredness.

Steczkowska electrifies and permeates human sensitivity. During the concert, she constantly changes, enchanting with her voice, which seems to have no limits.
