Since Melody Prochet released her debut album under Melody's Echo Chamber in 2012, the project began to define her. Produced by Tame Impala's Kevin Parker, the self-titled LP became overshadowed by Parker's involvement. The end of their relationship brought the media and fans into private matters in a rather unusually invasive way (something Prochet hasn't necessarily shyed away from commenting on via her instagram). She became known for a production sound that essentially belonged to her, but also to their collaboration and everything that followed.

Now, it makes sense for Prochet to be looking for some reinvention. That's why "Cross My Heart", the first single off the upcoming Bon Voyage, could not be more different from the Melody's Echo Chamber we have come to know and love - in a good way. The single was announced via Prochet's instagram page with the caption "happy birthday", as it was released on her 30th birthday.

At a sprawling 6:54 minutes, the psychedelic track finds itself in the middle of French pop, 00's electronica, 70's rock and even a good old flute solo somewhere in there. The song begins as a re-introduction to Prochet's effortlessly whimsical vocals, making you think it's headed in one direction before finding out that there's several. The mixing and matching of genres, all within their own cohesive flow, showcase her extensive songwriting ability that's only gotten better and better in the last few years. A haunting high-pitch synth dominates the second half of the song, one that will easily leave you in a daze. It's a six-minute psych jam in it's entirety - one that hasn't been done before, and that's hard to say.

Despite the jam-packed sounds, "Cross My Heart" doesn't lose itself. It still feels like a true evolution of Prochet, one that could've easily fit on the first record, in another life. Aside from writing, producing and recording the album herself, she also enlisted a few pro's - Fredrik Swahn (The Amazing), Reine Fiske (Dungen) and Gustav Ejstes (Dungen).

Even if it took four years, it was well worth the wait. Prochet has clearly pushed the boundaries for herself as a songwriter, and that makes Melody's Echo Chamber all the more of an interesting project to follow. Bon Voyage will be self-released by Prochet this year, and while there's no set date yet, we're already on the edge of our seat wanting more.
