Finnish orchestral metal band Apocalyptica's latest studio album is befitting of its title; "7th Symphony" is the seventh symphonic offering from the classically trained cellists and percussionist. This time around, the act boasts even more impressive instrumentation than 2007's "Worlds Collide." The 10-track album contains strong guest vocals by Bush's Gavin Rossdale, Shinedown's Brent Smith and Slayer's Dave Lombardo, but the instrumentals are just as gripping. The set opens with "At the Gates of Manala," the first of five instrumental tracks that make up half of the set. Later, Rossdale lays an anthemic chorus over descending power chords and cello injections on the first single, "End of Me," while "2010" (featuring Lombardo) opens with an eerie-sounding cello and guitar before sliding into grandiose metal percussion. With production by Joe Barresi (Coheed and Cambria, Queens of the Stone Age) and Howard Benson (Three Days Grace, My Chemical Romance), Apocalyptica continues to impress with its unique ability to meld classical with metal.
