He actually didn't specify a time period, he just wants music the crowd can relate to. Being 33, and visiting the bars in my area, I can agree with the people who say a lot of Classic Rock still goes over very well. True people my age grew up with Nirvana. I saw them when I was 16. But it's not necessarily what I consider 'party' or 'drinking music'. And definitely not dancing music. That is what people want to hear at the bars here.
