Never heard of The 5 Spot's debaucherous late-night dance parties? If not, then your head is probably fedora-less, and your jeans are likely of a relaxed fit. Each Monday night, the crew of vinyl-spinners known as Electric Western Presents kicks out superlative dance tunes from soul to doo-wop to '50s rock 'n' roll. And, without fail, said tunes and an ample supply of booze get East Nashville's most irony-loving, shitty-day-job-having, beer-swilling, fixed-gear-bike-riding gadflies leering at one another with a modesty level typically reserved for the subjects of televised nature specials. That isn't to say the Keep on Movin' parties aren't a blast, and it certainly isn't to say we never attend. Not that our obliterated brain cells will allow us to recall any of it. Besides, there ain't nothin' wrong, as they say, with a little bump-and-grind. D. PATRICK RODGERS
