DragonForce celebrates 20 years of Inhuman Rampage at House of Blues Houston with Ensiferum and Rhapsody of Fire joining the bill. The show centers the album that pushed the band's rapid-fire guitar work and huge power-metal choruses into a wider spotlight. With three established acts sharing one ticket, this is a full evening for fans of speed, melody, and theatrical metal. The concert starts at 6:30 p.m., so arrive early enough to catch the opening performances rather than only the headliner.
