We found that if you played a bunch of punk singles in a row, people would dance like crazy and then get worn out and go somewhere else in the house. And if you played reggae all the time, people ended up leaning against the walls and nodding their head. But if you mixed it up, the floor got more and more packed, and the energy from the two types of music seemed to feed into each other, and the adrenaline from the punk, and the seductive sway of the reggae seemed to fit together.
