looking forward to making it because I think it will sound so different from anything I've ever heard before". Other projects and contributions Thordendal has featured in numerous side-projects, such as XXX Atomic Toejam with Petter Marklund. The project had released a 7" two-track single "Celebration" under the name Sepülchre Inc., then took the moniker XXX Atomic Toejam and issued an MCD entitled "A Gathering of the Tribes for the First / Last Human Be-In" on Cold Meat Industry and also featured a track on the "Karmanik Collection" compilation. A full-length album was long announced, but never surfaced. Thordendal also played bass for Petter Marklund's solo project Memorandum and together with Marklund remixed tracks on the 1995 compilation album "Ars Moriendi". In 2010, Fredrik recorded some drum tracks with Morgan Ågren [of Swedish prog-rock band Kaipa] and [Soilwork's] Dirk Verbeuren. Several of Fredrik's demos have been released on the internet as MP3s or as videos on YouTube. One composition entitled "Demo 33" can be found at https://www.youtube.com/watch?v=aYkSb7wtj0E. "Demo 33" was used to demonstrate Fredrik's MIDI breath controller, which is used on several Meshuggah songs, one being Future Breed Machine. More information regarding the controller can be found at http://www8.tfe.umu.se/personliga/jh/index.html (along with the original "Demo 33" MP3 and other demos of the device). The site was created by Johan Haake, brother of Meshuggah drummer Tomas Haake, and the creator of the original MIDI breath controller for Fredrik. Another demo idea, called "Secrets of the Unknown" can be found at https://www.youtube.com/watch?v=sMUXa6Q7B6I.

Thordendal features in the Darkane track "Psychic Pain" from the album Insanity, performing lead guitar. Thordendal also contributed to the song "Asphyxiate" which can be found on Scarve's album Irradiant. He played a guitar solo on the title track of the Devin Townsend Project album Deconstruction.
