"Martin" follows on from last month's lead single "Can't Cool Me Down".
The new offering arrives with a video that sees Will Toledo do some washing up as his alternate persona Trait.
Making A Door Less Open will be Car Seat Headrest's first album of new songs since 2016's Teens Of Denial. In 2018, the band released Twin Fantasy (Face to Face), a rework of their 2011 LP Twin Fantasy.
The album was created over the course of four years. The band recorded the album twice with their side project 1 Trait Danger - once live with guitars, drums, and bass, and once in a MIDI environment using synthesized sounds. The two albums were merged during the mixing process.
Toledo has also released a statement to go alongside the new album.
