Boris's 'Rainbow' is a sonic masterpiece that embodies the band's eclectic and experimental approach to music. Released on 22 May 2007 via Drag City Records, this 43-minute album is a testament to Boris's ability to blend disparate genres into a unique sound.
'Rainesia' sets the tone for the album, followed by the title track 'Rainbow', which showcases the band's capacity to craft mesmerising soundscapes. Tracks like 'Starship Narrator' and 'My Rain' demonstrate Boris's penchant for noise rock and drone, while 'Shine' and 'You Laughed Like A Water Mark' exhibit a more subdued, shoegaze-inspired quality.
The album's latter half is marked by the intense, sludge metal-infused 'Fuzzy Reactor', which gives way to the melancholic 'Sweet No. 1'. The closer, 'No Sleep Till I Become Hollow', is a haunting culmination of Boris's doom metal and stoner rock influences. Throughout 'Rainbow', Boris seamlessly navigates the realms of post-rock, creating an album that is both a showcase of their technical prowess and a deeply affecting listening experience. With 'Rainbow', Boris has crafted a work that is at once beautiful and brutal, a true reflection of the band's innovative spirit.
