The hip-hop group Atmosphere was announced as the third and final W.I.L.D. artist on Wednesday at midnight on Social Programming Board’s Facebook, Twitter, Instagram and web pages. Atmosphere, which consists of rapper Slug and DJ Ant, will begin performing at 8:45 p.m., following Yeasayer and Mat Kearney, as the final act of the concert.

Reviewing the new, festival-style line-up

So just over a week before the event itself, we finally have the full roster for this year’s spring W.I.L.D.

Yeasayer established themselves firmly in the eclectic music scene after the 2010 release of their much-acclaimed “Odd Blood.” The Brooklyn (where else could they come from?) six-piece was quickly solidified in the hearts of obscure and indie music fans everywhere, citing their fusion of world music, 70’s psychedelic trance and synth pop.
