“A LETTER” is the 9th track on iDKHOW’s album GLOOM DIVISION. It is a reworking of a Brobeck’s song of the same title. The song, originally from 2005, has been a live staple in iDKHOW’s setlist for years. Dallon shared the following via a RockSound interview:

I had always imagined this bit where the audience harmonizes and does this sort of choir bit. And when I was playing with The Brobecks, we were never performing for that many people to do it properly. So when the iDKHOW shows that we were
playing began to have enough people, I thought that maybe this idea that I’ve had for 10 plus years can finally come to be. So we started doing it and it worked. It was beautiful. And whatever the song had been written about beforehand became less important. The song became more about sharing this moment with the audience. Now, a roomful of strangers, regardless of whatever kind of differences you may have, at least for this moment, right now, we’re going to share this and we’re going to harmonize together and we’re going to work together. And to me, that’s a really beautiful thing. So that’s what I love about it. That’s why we play it, and that’s why I wanted to put it on the record – to give it a proper chance.
