"Ska War," Prince Buster (featuring Toots and the Maytals) 1964, Blue Beat.

Here's that old trick of dance music. Turning sex machine-like repetition and even monotony into ecstatic dance grooves, a cultural form of momentary physical liberation as old as village societies. This record sounds like they could be recording the scene on the cover. A big sound system booming from outside the shot. Prince Buster and Toots from Toots and the Maytals are MC'ing, toasting back and forth about the "jungle" and taking it to "Broadway." The dancers are shouting and chirping rhythmic accents, like they were cheering and chiding each other on to the unmitigated glory of shaking your thing. Goofing. Lots of laughter. Effective dance grooves make repetition, that often feels rote and like tedious overkill to those unmoved by its pulse, feel involuntary and wonderfully compulsive to dancers and dance music lovers. This rustic ska reggae jam clocks in at a traditional pop song 2:53 but feels like all great dance music: like you never want it to stop. "Come fly with me." Sublime.
