Mike Mangini is a drummer/percussionist from the band Dream Theater. He's considered one of the worlds fastest drummers in the world. He is a virtuoso. Bruno Mars is just an average artist that happens to be famous at this current time. He's mediocre at what he does.
+Piadina Funk True, but mediocre is mediocre. Bruno Mars isn't recognized as a drummer or percussionist. Of course the people who have seen much better drummers will criticize him. He's mediocre.... And he's playing in bigger stadiums than much better drummers... And he's showing off to people that don't know much about drumming so they will worship him even more. Why not let better drummers show off on a much bigger stage? That is why we criticize.
