During that time, Leviathan and Ellefson had many discussions on who should sing on the songs. During one of those discussions, Ellefson had mentioned the name Lance King. After listening to some of King's work with previous bands, most notably Balance of Power, the two immediately realized that King would be a perfect fit for Avian. Ellefson contacted King and explained to him what he and Leviathan were doing. King seemed interested and was sent two songs to record vocals on. When Leviathan and Ellefson heard King's vocals over the songs, they were impressed and immediately asked King if he would do all of the songs. Since King and Ellefson had previously discussed working together at some point in the future, this seemed like the perfect opportunity to do so and King signed on to do all of the vocals on the album.
