Apocalyptica is a Finnish band consisting of three, formerly four, classically trained cellists and, since 2003, a drummer. Their speciality is metal music played on cellos (cello rock), though they also play classical music. They are all graduates of the Sibelius Academy in Helsinki.

Their first album, Plays Metallica by Four Cellos, consisted solely of Metallica covers. For their second album Inquisition Symphony, they added covers of Faith No More, Sepultura and Pantera, as well as three original songs. Cult followed in the same style of music. For their fourth album, Reflections, they developed their style of cello rock further; adding drums and developing a more electronic sound, instead of the previous acoustic style arrangement found on Inquisition Symphony and Cult.
