Epica is a Dutch symphonic metal band founded by guitarist and vocalist Mark Jansen subsequent to his departure from After Forever. They are known for their symphonic sound and the use of female vocals and male growls performed by Simone Simons and Mark Jansen, respectively. All six members write the music, but Mark Jansen and Simone Simons write most of the lyrics, which largely deal with philosophical topics, including science and religion, and world events. To date, Epica has released five studio albums (not including their instrumental album The Score – An Epic Journey ), with their most recent studio album, Requiem for the Indifferent, released on March 9, 2012.
