Lead singer Zac Lawrence says about the song: "More Heat! is about the way in which someone may attempt to convince themself they are feeling enjoyment from something that in reality is causing them a disturbance. Whether it be to preserve face, or simply through an inability to swallow their pride and accept that a spell of discomfort as a result of change far outweighs continuously doing something from which there is no contentment to be found."

"More Heat!" follows previous singles, "Relieved", "Mother", and "Mere Mortals". Later this year, DEADLETTER will perform across Munich, Vienna, Berlin, Antwerp and many other European cities before they land in the UK to play in Bristol, Manchester, Leeds, Glasgow, before finishing with a headline show at Electric Brixton on 16 November.
