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 2007, using bass guitar, some cheap drum machines, and synths. They were inspired to record music largely by ’70s synth prog, and ’80s lo-fi electronic and industrial music. They recorded a number of songs at friend Will Burnett’s studio that fall. Their first officially released track was on the Wierd Records compilation, Analogue Electronic Music Vol II.
