Symphonic remakes of powerful rock and metal hits have become quite popular, and for good reason. In keeping with the fad, <em>Symphonica</em> is a musical multimedia show combining the songs of Metallica, Nirvana, Pearl Jam, Deep Purple, AC/DC, Guns N' Roses, Aerosmith, Soundgarden, and Nightwish with a full symphonic orchestra. Among the performers will be the stars of <em>The Voice of Poland</em> singing competition show.
