“Hang Loose…Stay Loose” - People Under The Stairs
I went to an underground hip-hop concert last night and noticed that MAYBE only 40% of the people at that show were dancing! A lot of people didn’t even look intersted in what they were watching/listening!
Unless you’re being constricted by a snake, you have NO EXCUSE not to dance at a concert that is BUILT for dancing!

Elsewise, you should look like you’re having this much fun (all the time!):

and like this when you’re at a show:

(remember, if you feel you can’t do what’s above at a sold out/packed show, you’re just not trying hard enough) - use your elbows, it’ll make your objective loud and clear
Or at the least like this:

While relaxed, at least she rocks some smooth style!
Elsewise, the DANCE MONSTER will come and GET YOU!

This is the Encouraging Monster - he’ll hug you if you dance and squeeze you to death if you don’t!
Watch out for his cousin! He has a zero tolerance policy for not dancing
