The Sono Sion Band consisted of the man himself on vocals, Hasegawa Masaru on bass, Tanimoto Yukimasa on drums, model IZUMI playing keyboard and actor Okuno Eita (Roadside Fugitive) playing guitar. They were joined on stage during the set by special guests and fellow actors Gou Ayano playing guitar and Hasegawa Hiroki, who was last seen in Sono's Why Don't You Play in Hell?
In between songs Sono let slip some info on his new project, to be titled Love and Peace. It's due for release 2015 and, from what I could gather, will star all of the artists present on stage.
Whether this is a serious stab at starting a band or a shameless exercise in PR for his next movie I can't be sure, though I'd lean towards the latter. The music was punky and anarchic, though perhaps lacking in material, there was a lot of repetition in the short set, but it was fun nevertheless and some diehard fans in attendance clearly enjoyed it. I did see one guy's attempts at kicking off a mosh pit end abruptly after he violently head-butted the girl in front of him. How very Sono Sion.
