As implied by the title of the album, IV: Beyond the Reef of Sanity is the fourth full-length release produced by Swedish Kayser and delivered by French Listenable Records. Now, this is the second time that I have had the pleasure of receiving a release from Kayser and I must say that they have really stepped it up. Sure, the last album was great. But this one is downright fantastic. Still sticking to the somewhat traditional Thrash Metal routine, which I would describe as short, (somewhat) controlled aggression coupled with strong riffs, they have decided to (succesfully I might add) introduce several melodic aspects. This is most prominent on the track "Asphalt and Suicide", where a keyboard makes itself known and helps to add an extra dimension to the song. Not quite what I had expected, but quite a pleasant surprise nonetheless. On top of that, the band builds up momentum throughout the first nine first tracks of the album which they manage to keep continuously high; Which, all in all, makes for a very enjoyable album,
