Both bands contributed two new tracks to the EP. Converge contributed "No Light Escapes", a song that later appeared on the deluxe edition of their album All We Love We Leave Behind, as well as a cover version of Swedish death metal band Entombed's "Wolverine Blues". The latter was described by Converge's distributor Deathwish Inc. as being similar to "We Are the World"—a collaborative single from 1985 written by Michael Jackson and Lionel Richie, which featured numerous guest musicians. "Wolverine Blues" features guest appearances from Aaron Turner and Tomas Lindberg, among others. Napalm Death contributed "Will by Mouth", which is similar to the band's other material, and "No Impediment to Triumph (Bhopal)", which is a "slower and textural" song about the Bhopal disaster from 1984.
In May 2013, Converge self released an EP titled Pound for Pound: The Wolverine Blues Sessions, which was a compilation of the different vocal tracks that comprised its cover of "Wolverine Blues." It featured five songs, each of which had only one of the guest vocalists that were present on the split version.
