Left to the Unknown played their first show in early 2009. Starting as only three members, they went through a few line-up changes before settling on the current group that has led them on to bigger and better things.
After a terrible accident occurred to another Las Vegas local band, Cross Out These Eyes, LFTU was given the chance to play on a national ticket. It was their big chance to get noticed, and they did. With two guest appearances from the lead singer of Sanity is Lost and the guitarist of A Thousand Eyes Idle, the band was able to call some attention to themselves.
