Meshuggah followed up I with Catch Thirty-Three which is also a single song (over 45 minutes in length) but separated into 13 different tracks.
Meshuggah drummer Tomas Haake said of the EP: "That whole track was written and recorded just on random. Me and Fredrik would just jam on something, and when we found something that was kind of cool, he would walk into the control room. I would just record drums and it wasn’t a set pattern, I would just kind of stray away from the pattern, but just keep going in that vibe. Then we had to chart everything and go bar by bar to record the guitars afterwards, because it’s all just random."
Both the cover and disc artwork refers to the title "I". The cover features an "eye" and on the disc itself the word "aj" is printed, which is also pronounced the same way in Swedish as it would be in English and means "Ouch!". The "facial" structures around the eye are all made from multiple bent, shaped, mirrored and resized copies of a face.
