Venerable record shop Halcyon tosses a house-and-techno hoedown at Cielo. This time around, the gang is bringing in Palette Recordings' John Tejada, the West Coast vet who's one of the most inventive producers in the American techno scene, for a live set. Francis Harris, otherwise known as Adultnapper, recently released the beautifully emotive Leland on his own Scissor & Thread label; he'll be bookending the night, spinning both the opening and closing sets.
