As Los Angeles duo Riley Knapp and Casey Barth (together known as RKCB) continue their steady rise, they've teamed up with fellow duo Opia (made up of singer Cole Citrenbaum and producer Colorthought) for an entrancing new collaboration "Always."

RKCB is coming off a short stint opening for Gallant and they joined forces last month with Chicago producer Shallou on the standout cut "Slow."

As for the fusion of RKCB and Opia, it's a natural fit. And "Always" flows effortlessly, as if it's less a collaboration between separate entities and instead the creation of kindred spirits.
