Following the first release of Yuri's Black Soshi concept photo yesterday, SM Entertainment continues the hype by releasing the second blast of concept photos, featuring SNSD's leader and maknae, Taeyeon and Seohyun. Starting from March 11th, Black Soshi concept photos of each SNSD member will be unveiled sequentially until the 15th. The Black Soshi concept will be for a new song that's not included in their Oh! album and will be released on March 18th. The girls will not be on music shows as they prepare for their Black Soshi comeback next week! But Yuri and Tiffany will still be hosting Music Core this Saturday. The teaser is expected to drop on March 16th.
