 Thirty Seconds to Mars retreated to the isolation of Wyoming's countryside in 2001 to record the album, tentatively titled Welcome to the Universe. The band and Ezrin chose an empty warehouse lot on 15,000 acres, starting an intense period of preproduction focused on fifty songs. The isolation allowed the band to work at a different pace. Jared Leto said that while recording in Wyoming, "there was an interesting dichotomy, a kind of contradiction with the technology and the organic world that we were surrounded [...] It's something that I think ended up in the music". Ezrin helped the band to understand the importance of an album's structure and how to create a progression, rather than a simple series of singles. "We really wanted to create something that had depth," Leto explained. He described the process of working with Ezrin as tumultuous but also fulfilling, having its own dynamics. He also stated that Virtue was a key element in helping the band define their sound.
