THEE MICHELLE GUN ELEPHANT, which debuted with "Sekai no Owari" on February one, 1996, starts the 30th anniversary project "THEE 30TH" on February one, 2025, with the theme of "96k24b, 180g & 4K." They convert their sound sources into high resolution for digital distribution, release analog editions on heavy vinyl, and upconvert their past music videos into 4K high image quality in order to leave their works as a permanent preservation edition. This work compiles on CD, for the first time in cardboard sleeve jackets, the remastered sound sources of nine original albums they have released so far. Furthermore, they remaster coupling songs and alternate version songs that are not included in the original albums and newly produce them as "RUMBLES" It is released as an 11 CD box set.
