Secrets of the Moon have had "post-metal" leanings for the last several albums now, but never allowed it to overtake their patented sound of gloomy, melodic Black Metal. However, going into SUN expecting Seven Bells - Part 2 will leave many a listener disappointed and perhaps a bit baffled.

SUN starts off with "No More Colours", a track that wouldn't have sounded out of place on Antithesis, but with "Dirty Black" the album takes a turn for the different. While the main melodies aren't much different from past Secrets of the Moon releases, the leads are cleaner while the riffs and drums are less aggressive. The vocals are perhaps the biggest change. Besides the opening and closing tracks, the traditional Black Metal style is all but gone, replaced with a slightly off-key croon (bringing Quorthon to mind).

SUN is enjoyable enough, especially for the open-minded, with memorable songs throughout, but Secrets of the Moon are still highly likely to lose some fans with this album, as Black Metal this is not.
