By the album's release, the band had experienced several member changes: drummer William Marrufo had been replaced by Andy Mendoza, and MC Chali 2na, turntablist Cut Chemist, and saxophone player Jose Espinoza had all left. With no official MC for the rap vocals, the band used a variety of guest MCs on the album, including Kanetic Source. Percussionist Justin Porée also did some of the rap vocals for the first time. Rene 'DJ Spinobi' Dominguez also appeared on turntables as a guest. While touring for the album, Kanetic Source and DJ Spinobi both joined the lineup.
