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 features Bannon , Ballou and Newton as well as guests Tomas Lindberg , Aaron Turner , and Kevin Baker all on vocal duties . Due to scheduling issues the band found it easier to record each vocalists duties separately to be edited together later as it is on the original track . The track 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 . " On May 23 , 2013 , Converge self-released the EP , '' 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 , with the exception of Lindberg and Ballou who share a track . 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
