K.K. Works 1998-2000 is a compilation of tracks by Kahimi Karie recorded in the title years. It was issued in 2001 by the Japanese major label Polydor.
The songs are from the full-length albums K.K.K.K.K. and Tilt and the EPs Journey To The Centre To Me and Once Upon A Time (collaborations with Momus and The Olivia Tremor Control, respectively). The version of Momus' "Pygmalism" found on the K.K. Works album is taken from a remix CD issued with the rare multi-media collector's item K.K. Limited Edition 2000.
