well since the clubs are tightpack, soda/beer all over the floor, and live bands that insist playing 12 minutes song, there is little incetive to go to them.
A salsa dancer needs: Clean wood floors, Good dancers and Good music, socials provide these so we go there.
Once I tried to make it to a Brooklyn happening club, there was an hour wait line, $20 dollars cover, incredible loud loud music, no place to dance.
I will go to watch/pay for a live band to chill and listen to the music, but for dancing I take a good DJ any day. I have yet to find a live band that caters to dancers, by making their songs dancer friendly, I appreciate that they are there to highlight their band, and their members with their interminable solos, but the dancers needs are such that the bulk of dancers wont see live music with the same appreciation that says... listeners may have.
