Query: Difficult music that needs repeated listening

"The sky moves sideway" represents Porcupine's experimental era.Steven Wilson Composed long difficult suite (title track) and a few shorter tracks.the suite is interesting, very emotional but sometimes it becomes a bit boring and slightly too long - but it doesn't changes that all album is very good.Title suite along with paranoic rocker "Dislocated day",dark moody ballad "the moon touches your shoulder" or ambient influenced hypnotic "Moonloop" are making this album.Steven Wilson (vocal,guitar,band's leader) shows his abbility to connect many ideas into one huge great piece of music.This album needs repeated listening.it may seem boring and pointless but after some time you wil get used to hypnotic dreamer atmosphere that this group creates on this album (and on others too).
