Oozing with the heart-shatteringly powerful emotion that Fitzsimmons has down to a T, "Beacon" echoes around its hallowed surroundings with muted rage.

Speaking of the track, Fitzsimmons said:

"It's a pretty angry song. Or at least angry for me. It's a song about not wanting someone to leave but being willing to be there for them when they do. I remember the Death Cab song ("I Will Follow You Into the Dark") coming into my mind around that time and being really pissed off at how wrong the idea of being able to follow someone into death is. The line in ‘Beacon’ which says "where I cannot follow anymore" is meant to be a correction to that idea. No disrespect to Ben, he's one of my favorite writers, but In the moment of grief, when I desperately wanted that sentiment to be true, I saw that it was not."

Pittsburgh, the mini-album he recorded while mourning the loss of his grandmother, is out now via Grönland Records. Fitzsimmons will perform at London's Scala on 11 August.
