This one is the China Music Valley Festival, which is run by a State run company, Gehua and American Entertainment company, Live Nation. Irrespective of how well it went, the poster certainly looks the most slick and professional in Beijing, and was designed by SHOWHY.
I think it shows a level of design maturity, and it grabbed my attention when I walked past it in the subway. Clear and bilingual, I can see a clear sense of hierarchy between the big acts and small acts. Nice work pengyou.
