Knock Knock fuckbois. Who’s there you ask? It’s one of Denver’s most exciting young artists, YaSi. You may remember her from the wavy visual for “Pink Caddy“. “Knock, Knock” however, is a decided change in direction for the soulful songstress. The angelic vocals and smooth delivery are still there, but YaSi also showcases some serious bars on this one. With a rapidly growing fanbase and an ever-evolving sound don’t be surprised to see her make some serious waves with this one.
