It's been a brutal year for local nightlife insitutions, to say the least. First, Axis/Radius' proprietors pulled the plug on the iconic Scottsdale dance club in late June. A month or so later, venerated Mesa music venue Hollywood Alley ceased to exist in early August after its owners were forced to close the place due to financial woes. And after this weekend, Martini Ranch, 7295 East Stetson Drive in Scottsdale will become the latest long-running after-dark destination to shutter, after more than a decade and a half in operation. The combination concert hall and dance joint, which has gone through a number of ups and downs since opening in 1994, is days away from closing for business and being sold to new owners (who reportedly will renovate and re-concept the place). Before that goes down, however, the two-night "Curtain Call" celebration will take place this weekend featuring DJs of the both the longtime-favorite and special-guest variety in the second-floor Shaker Room. DJ Randy will offer one final spin session in the "club within a club" on Saturday, October 12. And then the final night on Sunday, October 13, will include performances by frequent Martini Ranch guest selector DJ Spryte and Old Town legend DJ Fashen. The last blasts start at 9 p.m. each evening. Admission is $5. Call 480-970-0500.
