The thing that humanity clings to is hope. In the darkness, light will prevail. In uncertain times, prosperity will ultimately endure: without it, there is simply nothing. On 'Blue Garden', Delta Sleep's 4th studio album, out 27th September on Sofa Boy Records & Wax Bodega (US), the band find themselves digging beneath the overwhelming darkness of the world to find just a glimmer of light tying in similar themes across their expansive back catalogue to become what is perhaps their heaviest record to date. Throughout, Delta Sleep weave their way through moments of dark and light, interlaced with a sweeping ambience and complex tempos that are inspired by punk, indie and electronic influences yet reminiscent of the math-rock home they belong to. In true Delta Sleep fashion it's structures and textures are moulded to their sound - on 'Figure In The Dark' it's the crashing drums juxtaposed with warm harmonies that make it an emotionally purging listen, while the R&B infused rhythms in 'The Distance' helps to push this record past the boundaries of anything they have done before. On 'Sunchaser' the mood is brought to a heightened crescendo as gorgeous guitar melodies garner a sense of melancholic longing before making way for a chorus that dazzles to life like a beacon of hope.
