"Russian funk! There's plenty of heavy drums at the start of "Delirium" – really making for a chunky rhythm at the start, while guitar carves out the main element, alongside spookier organ lines, bass, and some nice percussion fills! The percussion returns heavily on "Congolian" – leading off the tune with the bassline, as a great way to set things up with plenty of richness at the bottom." - Ear Candy Music
