His voice is truly good, and he is just nine! He may be able to sing for many years before voice change.
Now the sound has been quite different from that when he was seven, and the way he sings is different, too.
Compared to Francis Bernier, he seems to be more active.(?)
I don't really reminded Francis Bernier by Jacob Guay. They release their first albums at similar age, but Francis Bernier's singing sounds just like his age, at the same time, Jacob Guay's display sounds a little bit overage.
