Just had a listen to his performance. I was disappointed, because he has the perfect voice for it and he is capable of better.
His choices musically were hit and miss. His timing was off in a few places, and the riffing made him fall off the melody a few times, which distracted from the song and from how amazing his voice is.
I love listening to Andrea and think he is great at his best, my favorite singer of the season,in fact,but if his voice was anything less than spectacular, it wouldn't have worked .I was still impressed, but, though there were moments of brilliance and wow factor, only by how great the instrument is,not by the delivery.
