Biography
Not much is known about Life Sim - it's thought that it's made up of certainly A. G. Cook and another second member (potentially Finn Diesel).
Their single, "I.D.L." was released in 2015, alongside a remix by Thy Slaughter (made up of the already-mentioned A. G. Cook and Finn Keane - not to be confused with Finn Diesel). "I.D.L." is thought to stand for "In Digital Life".
