Lines Written in Code《密眸》是Nocturnes曳取既上半年EP发行之后，问世的第一张正式专辑。在保持了歌曲听感丰富性的同时，整体氛围和调性更加统一，曳取的风格也更加凸显。专辑收录了从2016年下半年至2017年上半年创作的八首新歌，和2016年发布EP中的两首最佳单曲。
Nocturnes debut LP, Lines Written in Code, is a "sensual concoction of haunting vocals, impeccably groomed arrangements and nuanced piano chords", an immediate opening statement of intent to the listener packaged in a sound that is all their own. Equal parts Foals-esque Indie Rock, Bonobo-inspired electronic beats and Coldplay-driven pop sensibilities, Lines Written in Code showcases one of the Chinese music scene's brightest new acts.
Lyrically, Lines Written in Code explores the disconnect between our desires and our actions, the things we wish to say or do but never have the courage to act upon. It is an album of silent heartbreak, missed opportunities, realities that might have been. None of this is more apparent than on Echoes, the track from which Lines Written in Code takes its name. The song is a soliloquy that never was, with singer Leslie imagining what might have been between her and the song’s subject many years ago.
