Tomorrow's Harvest's announcement was marked by a cryptic advertising campaign and scavenger hunt beginning on Record Store Day 2013. The campaign revealed information about the upcoming release through the discovery of six strings of six-digit numbers. Four of the six codes were released to BBC Radio 1, NPR, Adult Swim and the fansite Twoism, another was released through an extremely rare unannounced 12" record containing a brief snippet of music and the code, and a sixth code was featured in a YouTube video. The combined codes were used as a password to gain access to an exclusive video and link to pre-order the album.
On 23 May 2013 'Reach for the Dead' was released as Tomorrow's Harvest's lead single.
