This international quartet represents the Portuguese jazz breakthrough that produced a group of improvisational music luminaries. That breakthrough was inspired by the Clean Feed record label founded in Portugal at the turn of the century. The albums released by her paved the way for the leader of this quartet, the Portuguese drummer Mario Costa, to enter the international jazz scene.The elite of modern jazz is represented by this entire group, which recorded M. Costa's original album Chromossome in early 2023. Its name symbolizes the interplay of the project leader's creative streak and the DNA of his three exceptional stage partners. Chromossome's music is much more than the sum of the musical parts of the quartet members."These are very inspiring compositions. There are no unnecessary notes in them. Each musician gives and receives what is needed, as in a perfect democracy. I can feel with what pleasure they play. It's magical," said Italian jazz legend Enrico Rava at Chromossome.
