It seems like practically every show I see either local or professional, with the exception of jazz, the drums are too loud. You always see the drummer smashing away back there and in my opinion it makes everything sound bad. There's no room for anything else and the mix quickly goes to hell. All you can hear is drums and cymbals, goodbye separation of instruments. Can drums play too quiet for gigs? Maybe if you're playing with a loud band you could be drowned out, but still I'm not too sure. It seems like if drummers played quieter the music would sound better.
