Hubert Spięty Dobaczewski started in the band Koli, then Lao Che, and for the last few years, he has been creating solo material with his backing band. After albums such as ‘Antyszanty’ and ‘Black Mental’, he has prepared ‘Heartcore’, setting himself a new musical and lyrical direction that may surprise listeners with its intimacy but also meet with their favor, as exemplified by the presence of the song ‘Blue’ for 30 weeks on the 357 Songs List, more than half of that time at number one.
