A Life Once Lost is a five-piece band from Philadelphia. They started as a metalcore band before the scene became huge and after their first album, Open Your Mouth for the Speechless, came out on the indie label Robotic Empire. They then signed to Deathwish Records, (Converge's lead singer Jacob Bannon's label). When A Great Artist came out, they had evolved into a Meshuggah influenced band, still featuring a hardcore bite but with plenty of tempo changes.
