Tokyo's Coolest Sound

Advocates Bar, located in Shinjuku 2-chōme (Tokyo's famous gay area), will host an event paying tribute to Konishi Yasuharu! All DJ's should be playing mostly (if not only!) Konishi works!
Sounds like a must-go for Konishi fans!

Early-goers will be given a special mix CD by Hirabayashi Shinichi.

A bit of trivia...
This "concept" blurb at the event's official site contains several popular nicknames for Japanese artists Konishi-san has produced: Kyon-kyon, Fuka-kyon, Ayaya, Fu-min, Akko, Fifi, Matsuken.
How many can you figure out? :)
