Willie Burns + Beautiful Swimmers

WT Records head Willie Burns (William Thomas Burnett, who also records as Speculator, Black Deer and Daywalker) is one of the key figures in Brooklyn's experimentally minded (and fast-growing) dance-music microcosm. Another key is the local L.I.E.S. label for which he sometimes records, which is also represented tonight by duo Beautiful Swimmers. And all for the price of, um, free.
