 The "I" EP contains a single, 21-minute song of complex arrangements and was a hint of the forthcoming album, 2005's "Catch Thirtythree".The EP, which has never been played live by the band, was written and recorded during jamming sessions of Haake and Thordendal.On "Catch Thirtythree", Meshuggah again used eight-string guitars, but utilized programmed drums for the first time also for the release, with the exception of two songs from 2001's compilation "Rare Trax".
