Led Er Est emerged from a series of jam sessions that core members Shawn O'Sullivan and Sam de la Rosa started having in early 07, using bass guitar and some cheap drum machines and synths. They were inspired to record music largely by 70's synth prog, and 80's lo-fi electronics and industrial music. Owen Hutchinson joined the band for their first live show, at the Wierd party that December. In November of 09' Wierd Records released their debut full length. In spring of 2010, they toured Europe with Xeno and Oaklander, playing shows in the UK, Belgium, Germany, the Czech Republic, and Italy.
