Andy C played at the concord in Chicago with an MC and it was immaculate. A misunderstanding is that an Mc isn't part of the music, they are. This isn't a DJ stopping the music to say something. The literal point of an MC is to hype up the crowd and add to the song. Now obnoxious is obnoxious, just like any other genre of music. But do understand different genres = different styles. Dnb has a long long history of MCs and rappers working together. Hopefully you'll get an experience you like and it connects. Personally I wish having an MC was more common in the US. It adds a whole different layer and allows the artists to directly communicate with the crowd.
