Yeah there is no doubt about her perfect voice execution in En Concert, and I agree practice here I think is the issue, Im pretty sure Mylene trained her most of the time and got her voice to a great level, today with the absence of Mylene she has to find her ways to practice her voice and get it to the great level she still can have
.The original music of her songs were composed for her and her voice, all the songs go smoothly and are wonderful, hopefully she can reach that level once again
