Rin Toshite Shigure (凛として時雨) is a Japanese rock band. There are two English spellings of the band's name, causing constant confusion among non-Japanese speaking JRock fans. The theoretically correct spelling, based on the kanji in the band's name, appears to be Rin Toshite Shigure, but the band uses the spelling Ling Tosite Sigure on their website instead.
For now, all info on the band is located at the Ling Tosite Sigure page.
