Braving the tropical storm that is Rock in Rio, Helloween unleashes their unique brand of power metal upon the masses. The stage is a whirlwind of long hair, leather, and lightning-fast guitar solos. Deris, a whirlwind of energy, commands the crowd, his voice a clarion call amidst the chaos. The band's synchrony is uncanny, each musician locked in a trance, their instruments extensions of themselves. As the final notes of "Keeper of the Seven Keys" fade away, the crowd surges forward, hungry for more, but Helloween has left them wanting, their performance a fleeting, thunderous dream.
