Despite the obvious handicap of having no vocals, there has been an uptick in the number of instrumental bands in recent times and more often than not, they play a ‘post’ variation of metal. In case of the Belgian four-piece Hemelbestormer, the choice of style lies close to the grimy underbelly of sludge metal. ‘Aether’ is the band’s debut full length and with four long tracks, the record comes off more of an experience, than a traditional record. The music has a strong melodic flavor with a lot of ambient and heavy sludge passages thrown in and at the time of listening to the record, the riffs manage to do a decent job of entertaining the listener. Then again, the problem with not just Hemelbestormer, but most instrumental post metal bands is regarding the memorability, which ‘Aether’ is not exempt from.
