Last Saturday, Anamanaguchi and Meesh played night two of Game Over, a social gaming event put on by Game Over Entertainment, at the Boston Center for the Arts. Flickering screens from the dozens of arcade games helped set the playful and colorful atmosphere, furthered by the band’s glowing neon lights, flashing visuals, and cascade of balloons during “Pop It,” making it a unique and thrilling show for the crowd of nerds, gamers, and music lovers.
