Mit "Shook!" stellt die Alternativeband SYLAR einen weiteren Vorabsong ihres aktuellen Albums "Seasons" vor, welches ab sofort via Hopeless Records zu haben ist. Zur Single sagt die Band um Frontmann und Saenger Jayden Panesso:
“'SHOOK!' is one of the songs we’ve been waiting to release the most. This one goes out to a ton of people out there. You know exactly who you are. Turn this one up to 11, and vibe with us. Here’s our new anthem”
