The whole idea behind DJ-ing is to be able to judge what people want to hear (next). This is true when looking for venues to play. You have to do your homework. Go to the place and see what they are playing now, talk to the staff, talk to the owner/manager what their expectations are, talk to some of the customers. Talk to other DJs in the area. In short, figure out what the place is about and adjust accordingly.
As you say it’s a bar, I am gonna take a wild guess here and say it’s probably not a genre-bar. This means they will most likely have an audience that likes a broader variety of music. Which would mean that even house as a genre could be too limiting and you are already talking about one single sub-genre.
So, if you haven’t done your homework locally, how can we possible suggest anything useful as far as picking genres is concerned?
Only if you are a producer you can and will have to get away with just sending the material you produce as that is your style.
But if you are a DJ, you have to figure this stuff out on your own and if you can’t (yet) you have to ask yourself if you are ready to stand in front of an audience and make it work.
