Some rappers just sound amazing together. Today IDK and Denzel Curry show their undeniable chemistry once again on a new track "Once Upon A Time (Freestyle)" and it's sounding amazing. When they announced a new song together I assumed it would be a hard-hitting scary track but they went chill on it and it's perfect. The two rappers deliver their lyrical verses back to back as they switch off throughout the song that has us hoping these two have more up their sleeves. Enjoy!
