I love Chris Cornell and as far as hard rock vocalist he has a case. But for vocalist with the most range I don’t know if he has the range to beat perry I don’t know Steve Perry has just always been one of my favorite singers. And Pavarotti is different from the other guy’s because he didn’t really crossover into other music but just listen to Turandot: nessun dorma and tell me if it’s not amazing the power his voice has.
