Each Golden Week, the folks at Roppongi Hills team up with radio station J-Wave to host a free live event – the eponymous acronym stands for Music, Art, Performance and (wait for it) 'a Series of Special Streaming Session Showcases'. Or something like that. The curator for the latest event is none other than Yukihiro Takahashi, one third of YMO and co-organizer of the annual World Happiness festival. Takahashi himself will be playing on the first day, when he appears as part of TYTYT, his group with Yuri Miyauchi, Hiroshi Takano and Tomohiko Gondo. Other artists on the bill range from soulful rocker Chu Kosaka to baroque pop ensemble 4 Bonjour's Parties to sweet-voiced J-pop singer Yuko Ando. And, yes, it'll cost you absolutely nothing.
