The Copper Chimney's getting down and dirty. Sorry, make that DJ Dyrti, a transplant from Panama City, Florida, who helped launch Club Ra last year and now is working with new manager Cord Townsend to transform the establishment at 9650 East Arapahoe Road in Greenwood Village from Tech Center-typical to nightclub knockout. In the process, they're turning things inside out at the building -- sometimes literally, as with the rooftop deck. According to Dyrti, Chimney owner Ahmed Ansari didn't know what a potential amenity he had in the upper-level area until Dyrti pointed out the sky-high popularity of patios at LoDo locales.

Now, in addition to the beautiful copper-and-brasswork bar, club-goers can enjoy a Technics 1200-based sound system, intelligent lighting and crazy Cocktail-meets-Coyote Ugly stunts from the staff, since Townsend and Dyrti have refocused the venue as a destination for high-energy fun. There's no dress code, but there is plenty of music, with tracks ranging from Motown to modern booty-shakers. Feel the energy at a debut party this Saturday, September 10, when the Chimney's sure to be smokin'.

The Tech Center has turned into club central, what with the Purple Martini opening a second outpost down there, then shutting its LoDo location (which will return in December with a new name). And now downtown's lost another lavender-hued lounge. Is it just coincidence that Club Purple, at 1523 Market Street, closed after Prince's grand-performance weekend? Owner Will Coleman was unavailable for comment, but a document referencing Colorado State Statute 38-22-105.5 has been slapped on the window of the club, by order of the word-intensive "Director of Building Inspection Community Planning and Development Agency, City and County of Denver."

Over in Cherry Creek, Agave Underground went all the way under this summer. Jack Duffy doesn't yet know what he'll call the new incarnation of the space at 250 Steele Street, but he does know it will offer more stimuli than Agave, the better to attract repeat business. And while he'll be the primary owner of the reconfigured spot, he'll still get a helping hand from his friends at Seven 30 South.
