The television series Portlandia infamously skewered the ubiquity of DJ culture with a sketch that became a viral video called "Wanna Come to My DJ Night?" Though that program is based in the Northwest, it might as well describe the prevalence of DJs at all skill levels who live in San Francisco.
Nayland Blake's art installation FREE!LOVE!TOOL!BOX! (through Jan. 27 at YBCA in San Francisco) explores the irresistible lure of being a DJ with a pair of turntables that's open for public play. The project is suitable for established DJs or for anyone who wants to try their hand at spinning. Simply sign up for a time slot on the YBCA site, show up, and have a ball selecting records to play from a collection of over 3,000 titles that Blake has assembled on-site. Performing on the open turntables is free with gallery admission.
No pressure, but your set will be streamed live online.
