Deathbeds

This Sempiternal bonus track features guest vocals from BMTH vocalist Oli Sykes' girlfriend, tattoo artist Hannah Snowdon. Apart from Swedish post-rockers Immanu el, she is the only outsider to contribute to the album. Sykes explained to MTV UK: "Our friends Immanu el do some 'oohs' and 'ahs' but there's no real outside guests on this album. It was a conscious thing not to have other people this time, just because we've done it so much on the last couple of albums. It was great having guests on but we didn't want it to be a gimmick - this time we wanted it to just be BMTH."
