Eluvium will release the long-awaited new double album, Nightmare Ending, on May 14 via Temporary Residence Ltd. Stereogum recently premiered “Envenom Mettle” from Nightmare Ending. The song features Explosions In The Sky’s Mark T. Smith who contributed guitars, noises, and samples to the track and was included on last week’s episode of NPR’s All Songs Considered. The Creators Project had Eluvium’s Matthew Cooper break down “Envenom Mettle” into several layers, and describe how he created each sound.  You can listen to the various parts and read the full feature at their website.
