For those who don't know what Yannick's musical style is, check out this link.
In the middle of the page you have a paragraph called "écouter les extraits (30s)"
Click on the 1st one "si tu savais" and then you have access to other musical extracts of his songs.
His shows are now very reputed and always quickly sold out. I'm personally looking forward to attend one in the nearest future.
