This album by Francisco Mela and Zoh Amba 'Causa Y Efecto, Vol. 2' is a celebration of differences and unity. Francisco Mela's singing on the traditional song 'El Cisne Blanco' could serve as a gateway to the world of avant-garde music. Zoh Amba's flute is as sweet and comforting as her saxophone playing can be powerful and mind blowing. These are two different artists from completely different backgrounds, showing us what unity-in-sound means, proving that creativity can foster peace and understanding.
