In January 2005, Weezer was in a significant phase of their career, having released their fifth studio album, "Make Believe," just a few months earlier in May 2005. "Make Believe" continued the band's evolution in sound, showcasing a pop-rock approach that diverged from the rawness of their earlier works, such as the eponymous debut and "Pinkerton." The live recording of "Why Bother?" from the Japan concert highlights Brian Bell taking on lead vocals, which reflects the band's dynamic nature and collaborative spirit. This era marked a transition for Weezer, as they began to experiment with different musical styles while maintaining their catchy melodies. The band's presence in Japan during this time also underscores their international appeal and growing fanbase beyond the United States. The performance in Tokyo captures the energy and excitement surrounding Weezer's evolving sound in the mid-2000s.
