As the final notes ring out on "Lost In The Sound Of Separation", it's evident that the six men of Florida-based metalcore band Underoath, (who have built their career on being both heavy and experimental since their inception in 1997) have delivered their most ambitious and accomplished disc to date. Succinct and resolute, there is little denying that the 43-minute, 11-track follow-up to 2006's rapturously received and gold-certified "Define The Great Line" is a hard music masterpiece.

Underoath, whose last three albums ("Define The Great Line", "They're Only Chasing Safety", and "The Changing Of Times") count combined sales in excess of one million copies, have worked diligently to reach this creative apex while building what may be the biggest metalcore following in the world. Through incessant touring and with a reputation for unrelentingly intense live shows, chronicled to perfection on the 2008 concert disc and DVD "Survive, Kaleidoscope", the band have forged an unbreakable bond with their fans. That allegiance earned the group a startling number 2 spot for their debut album on Billboard's Top 200 Album Chart for first week sales exceeding 98,000 copies and marking the highest chart debut for a Tooth & Nail artist. The band also earned a Grammy nomination for "Best Short Form Music Video" for the surrealistic video of the album's lead single "Writing On The Walls".
