When Prochet's previous project My Bee's Garden supported Tame Impala on their European tour in 2010, Prochet collaborated with Kevin Parker to produce her new solo material as Melody's Echo Chamber. The material was recorded in Parker's makeshift studio in Perth, Australia and Prochet's grandmother's seaside home in the south of France. The self-titled debut album was released on Fat Possum Records in the Fall of 2012.
In 2013, the debut album peaked at 61 on the US Billboard Heatseekers Album Chart. Q Magazine gave the album 8/10 calling it an "intoxicating listen that's well worth experiencing for yourself." Drowned In Sound's Dom Gourlay awarded the album 9/10 and stated: "Whatever happens next, she can rest assured safe in the knowledge that together with her beau they've conjured up one of 2012's--or any other year in recent memory--finest debuts."
In October 2014, Melody's Echo Chamber released "Shirim," the first single from her upcoming second album. In December 2014, it was announced that Melody's Echo Chamber would play at Levitation, the 2015 Austin Psych Fest in Austin, Texas but her appearance was later cancelled due to visa issues.
