Jun 25, 2008 Stepping up their assault on the Japanese airwaves, the dental students of Greeeen released A Domo Ohisashiburidesu in 2008 to wide acclaim. Their mix of happy pop songs and mildly hip-hop infused R&B met with the expectations of their newfound fanbase well, with tracks like the frantic opener, 'Sun Shine,' mixing higher-speed spoken deliveries with airy, major-chord riffs. GReeeeN is a Japanese pop/hip-hop four-member group signed to Universal Music Japan and managed by Edward Entertainment Group. The members’ identities are still unknown, as their faces have never been made public.
