Chase Matthew surprised the audience with Waka Flocka Flame during the final night of the Country Music Association’s CMA Fest on Sunday (June 7).

The country star performed on the free Riverfront Stage in downtown Nashville, Tennessee, and joined forces with Waka Flocka during his set. The pair will deliver a genre-blending collaboration at the end of this month. Matthew, 28, has been teasing “Hard Liquor” on his social media accounts, dropping hints at his collab parter before he revealed Waka Flocka joined him on the song. Matthew hinted that “it’s a rap artist,” and “NODODY in country has a song with this guy,” until now. He confirmed in time for CMA Fest that “Hard Liquor” with Waka Flocka Flame, 40, will arrive on June 26.
