The fact that this album is exclusively in Polish shouldn't put people who don't speak the language off, as this album shines both lyrically and musically. This is actually one of the most diverse albums I have heard, but it still manages to sound cohesive with its mix of psychedelia, rock, pop and whatever else. Iluminacja is greatly influenced by britpop... but especially by 60s rock music. However, fans of newer rock music will definitely find something for themselves as well, as Iluminacja is not just a cheap rip-off of The Beatles (although Big Day do have some references to that band, in this album the homage is given to the wild fade-out and fade-in of Indy-Rave), as the band plays this music in their own way.
