It starts like an alarm. 'Deleter' is the lead track from Grouplove's forthcoming fourth album Healer, and it is an emergency opener. It's fuelled by pounding keys, squalling guitar lines, and lightning drumming before the voice of Christian Zucconi questions everything around him: faith systems, his sense of belonging, communities, his own psyche. “All this time I thought you were a leader/It turns out you're only a deleter.” It could be interpreted as a political statement, but it's also highly personal.
