==Music video==
The music video was created by London-based team Shynola. It is the first music video not to feature the band members of HTDA, instead following a young man in a dystopian wasteland, as he tracks down and kills another man, to bring back his possessions to his ill mother. <!--will be expanded--> The video's production team said <blockquote>"We had a great conversation where the band articulated their ideas about modern identity, the effect of technology on culture and our inability to connect with others. We're fascinated by anthropology and coincidentally we had been toying with ideas for a feature film about a post-technology civilization, in which humans have reverted to primitive behavior. Sometimes things just fit together."</blockquote>How to destroy angels added <blockquote> "Their work is visually striking and consistently stands out. When we started talking about possible directors to work with for 'to be completedHow long,'their name came up right away. It's been an honor to finally work with them, and to get their wholly unique interpretation of the themes we've been exploring with this record and this song."</blockquote>
