 In mid-1999, Meshuggah performed in several Swedish concerts.The band started to write some new material but reported in mid-2000 that "songwriting isn't that dramatic, but we're getting there slowly".While fans were waiting for the next album, a collection of demos (from the "Psykisk Testbild" EP), remixes and unreleased songs from the "Chaosphere" sessions were released as the "Rare Trax" album.
