The Silver #01 STRUCTURE is a remix album featuring music from The Silver Case. It was released on April 20, 2001 and features 29 tracks composed by Masafumi Takada, as well as two remixes. STRUCTURE was reissued in 2006 with a number of previously unreleased songs, although neither remix was included. The original pressing was sold for ¥2500.
The two remixes are "Silver_Remix (Itoh's mix)", which was recompiled in The Silver 02 DESTRUCTOR as "Silver Remix [Bonus Track]". The other remix, "The Silver Case (Unplugged Ver.)", remains exclusive to the original STRUCTURE.
