John “Marko” Markovitch first found his love for music in high school as a founding member All or Nothing, which evolved into Stuck in Your Radio — a pop punk band that toured the East Coast and racked up millions of plays on YouTube & Spotify. After serving in the United States Marine Corps (USMC), John continued to keep guitar close, even while on deployment.

He later built an online following by streaming Pokémon GO on Twitch, but music never left his side. Having recently married the love of his life, John is now returning to the stage with On The Cusp, ready to take the Lehigh Valley music scene by storm.
