Olten are a band from Switzerland that plays a mixture of post metal and sludge and this is a review of their 2015 album "Mode" which was released by Hummus Records.
Psychedelic sounding drones start off the album along with some heavy riffs a few seconds later and after awhile melodic guitar leads are added into some parts of the tracks and clean playing can also be heard in certain sections of the recording and most of the tracks are very long and epic in length,
Most of the songs are instrumental except for one track and they are sludge style screams and the whole album sticks to a very slow musical direction while there is still a good mixture of both clean and heavy parts and as the album progresses synths can be heard in certain sections of the recording and they also give the music more of an ambient, experimental and post rock feeling.
Olten plays a mostly instrumental style that mixes post metal with the heaviness of sludge and the production sounds very professional while lyrics which are only used briefly are written in their native tongue and cover angry themes.
In my opinion Olten are a very great sounding mixture of post metal and sludge and if you are a fan of those musical genres, you should check out this band. RECOMMENDED TRACKS INCLUDE "Bol' zbeg" and "Gloom". 8 out of 10.
