I understand your point I mean, I know that things about the equality on DC (that's why Destiny Fulfilled is my fave record) I don't think they'll perform just Nuclear, I think they going to make a Medley (I hope isn't the same medley that they been made since 06). SMN, Survivor, LMB, Soldier & Nuclear I think is the correct medley. About Nuclear, Kelly's vocals on dat record are flawless, her voice and B's voice complement so good together is incredible how even their voices make a great team. I don't want to shade Michelle, but her voice is a bridge voice, she makes her part how she has to do it, no more.
But I'm sure that Kelly has nothing to lose this time, I don't see her like a backgroud singer, I see her as a part of a group like most of people. People always talk about Beyoncé, Kelly Rowland and the other one when they talk about DC. (Poor Chelle)
I'm from Latin America, that's why I talk so rude about Kelly's music when she tries to make herself a world wide brand. I think that Like This is more catchy, more friendly to every ears, isn't the case of KDL (I love this record, serously), and I understand that Kelly try so hard that been more and more successful on her own market but I'm so frustrated about her global career, since Commander she doesn't release a BIG ww single (Down For Whatever don't count)
