Drummer Trivett Wingo, formerly of The Sword, explained the reasons behind his abrupt departure. His resignation led to the cancellation of the band's tour in support of Warp Riders. He explained:

Not to get too specific, but my level of anxiety pertaining to being on tour got to the point where medication was not the answer. You can crunch Valiums all the time, but at a certain point you have to ask yourself if you should just be staying at home. I had been medicating myself to be on tour, and I realized that psychiatric help wasn't the answer. I was very deeply unhappy. I didn't want to sedate myself and do something that I wasn't enjoying. I figured it was better for me to finally listen to my inner voice and strike out on my own. I wanted to finish it all. If I had known what point I would break, I wouldn't have planned anything beyond that, but I reached my own personal breaking point as far as my panic and anxiety. I was living in a mental hell. I think it was really starting to affect my performance as well. I really officially completely burned myself down to a nub.
