When I first heard A Change of Seasons, I was completely amazed at how briliant the song was. I heard a live version of youtube so I thought the recorded version must be an absolute masterpiece, which it actually turned out to be.
The song itself was inspired by the death of Pornoy's (drummer) mother and contains a few lines from the poem "To the Virgins, to Make Much of Time" by Herrick. The theme of the song is carpe diem and the lyrics are really powerful.
Not only are the lyrics brilliant, but the so are the instrumentals, the song is very dynamic and layered, it's like listening to an epic of sorts. At a length of 23 minutes, one might think the song loops the same riff but it's so well written that it's actually like listening to several songs in succession with a really smooth transition between each one.
This album is a must for any prog metal fan, even thrash metallers will appreciate the sheer brilliance of this album. Even if this EP was just this song with some crappy leftovers tacked on, I would have still bought it just for the one song.
