Mad Gallica will debut her electrifying and visually striking rock “popera” experience at Raleigh’s Lincoln Theatre at 8 p.m. June 19. Mad Gallica was the longtime touring keyboardist and backing vocalist for the Grammy Award-winning Swedish hard rock band Ghost. Mad Gallica’s debut concept EP, “Enter The Vortex: Act One” (2024), was recorded with a symphony in Prague and showcases her genre-bending sound — cinematic, high-energy and vocally commanding. Her music draws comparisons to Queen, Nightwish, Muse, and Lady Gaga, combining classical elements with a modern rock edge. Advance tickets cost $24.95. Day-of price $29.95.
