Apocalyptica is a Finnish symphonic metal band from Helsinki, formed in 1993. The band is composed of classically trained cellists Eicca Toppinen, Paavo Lötjönen, and Perttu Kivilaakso, and jazz drummer Mikko Sirén. Originally a classical-style Metallica tribute band, the band eventually adopted a neoclassical metal style without the use of conventional guitars and bass. They have sold over four million albums to date.
