Rashinban is a Japanese psychedelic rock band led by Seiichi Yamamoto who is well known as a guitarist of Japanese experimental/noise/space rock/tribal drumming band Boredoms. The album features a lineup of feel-good pop songs that are far removed from the noise-focused expression that Seiichi Yamamoto has shown in his previous works in his other bands, such as Boredoms and Omoide Hatoba. However, beneath the gentle melodies, there is still a tingling tension and a sense of insanity. Rago is the debut album which featured a cover version of "Pilgrim's Progress" from Procol Harum's album "Salty Dog" with renamed as "HOWLING SUN".
