Technically, Heart Murmurs has quite good standards. Everything sounds clean, clear, atmospheric, moody and dark. There are some small issues with the general mixing and sound balancing, yet I am not sure if it was done on purpose or no. Anyways, I don’t think the listeners would realize or mind it. It’s too technical. Briefly, this is not the best possible, but a very satisfying outcome. Fauna Timbre is a band who will make a difference with the powerful atmosphere in their music in the first place, which is the most crucial thing, especially in this specific music style. When I take all these into account, I can say that Altering Echoes is a successful debut by Fauna Timbre with no doubt. They will easily earn the interest and the respect of those who are into atmospheric, doom, stoner, and progressive music.
