Joe and Mario Duplantier finished building Silver Cord Studio, Joe's New York recording studio, in early April 2015. It has become Gojira's recording studio and headquarters in America, joining Le Studio des Milans in Ondres. Audio files were created sporadically since late 2013 "on the computer in the tour bus", said Mario Duplantier; the new songs were a change in style for the band, as Joe experimented with clean vocals. The brothers began recording Magma, Gojira's sixth album, at Silver Cord Studio on 6 April. Ten days into recording, however, recording was suspended when they learned that their mother was ill and flew back to France.
