The album also served as a last project for the band's studio, Marcata Recording.  Marcata, which band members Matt Barrick, Paul Maroon and Walter Martin built in 1999, was located in a building owned by Columbia University, which took the property back in 2006.

It draws inspiration from some of the most abrasive-sounding genres, including hardcore punk, extreme metal, industrial and noise rock.  Grindcore is characterized by a noise-filled sound that uses heavily distorted, down-tuned guitars, grinding overdriven bass, high speed tempo, blast beats, and vocals which consist of growls and high-pitched shrieks.  Early groups like Napalm Death are credited with laying the groundwork for the style.  It is most prevalent today in North America and Europe, with popular contributors such as Brutal Truth and Nasum.  Lyrical themes range from a primary focus on social and political concerns, to gory subject matter and black humor.

Allmusic's Joe Viglione did feel, however, that "they seem to be trying to cover all the bases here," meaning that it had a variety of selections, including a standard from 1939 ("All the Things You Are"), a hit that charted in both the 1950s and '60s ("Hold Me, Thrill Me, Kiss Me"), a country crossover ("The Most Beautiful Girl"), and recent offerings from stage ("One", "Tomorrow") and screen ("Evergreen (Love Theme from "A Star Is Born")", "I Always Knew I Had It in Me"). A Special Part of Me is an album by American pop singer Johnny Mathis that was released in January 1984 by Columbia Records and reunited him with his "Too Much, Too Little, Too Late" partner Deniece Williams on one of the LP's two duets, "Love Won't Let Me Wait", which is also the only song on the album that was previously recorded and released by another artist.  This continuing trend away from the cover album genre would reach its limit with his next studio release, "Right from the Heart", which only had original material.
