Memory of a Cut Off Head is the twentieth studio album by American garage rock band OCS, released on November 17, 2017, on Castle Face Records. The album is the first to be released under the OCS moniker since OCS 4: Get Stoved (2005), and is their fifth overall to be released under an abbreviated name.
Produced by founding member John Dwyer, the album is primarily an acoustic collaboration between Dwyer and former core member Brigid Dawson. The album also features contributions from former drummers, Nick Murray and Patrick Mullins, alongside current bassist Tim Hellman.
Regarding the use of the name OCS and his return to the project's lo-fi roots, John Dwyer noted: "[Oh Sees and OCS] are two different bands honestly. Two different line-ups. The origin of the OCS came from this band [Orinoka Crash Suite]. We just wanted to get back to writing like that. But I also wanted to write a record with Brigid Dawson. I wanted to do something specifically with her. And it ended up being a lot of fun so I’m glad we did it."
