Kollaboration Acoustic 5 focuses on artists using their acoustic assets.  What does this mean? Artists must win over the judges for the title of "Kollaboration Acoustic 5 Champ" using solely their vocals and non-electric instruments, without applying synthesizers or computers for back-up. During the show, the candidates must choose songs that display their natural talent. Their challenge is to out-shine the eight other talented candidates, all of whom survived a rigorous round of competitions in March.  This week, I chose to highlight a video that demonstrates Kollaboration artists and the power of the human vocal range. Check out the male and female singers' remake of Yael Naim's 2008 hit "New Soul" into a beautiful harmony of voices.
