mariah barely tours but she sells so much she doesnt need to. Her biggest tour to date is adventures of mimi and that was only around 40-50 dates and it grossed 70-80 million which is pretty awesome but mariah's not a touring type artist! She never really was but people tour to sell albums? when you sold 32+ million albums why...tour? you already sold as many records touring is just a plus and in my opinion tiring as hell.
