Russian project Erthad, originating from Kazan, exists since the late 90's, but until now still hasn't made any official releases and preferred to stay in the underground, recording music only for himself and his friends. 'Gma' was recorded in 2002 with the use of voice and software noise synthesizers. If one says that the album's style is called 'ambient noise' - is to say almost nothing. The disc has a very specific atmosphere: this is a noise meditation, calm and detached from emotional fuss. An intuitive electronic pulse synchronizes with brain frequencies, rising and falling waves of non-aggressive white noise pacify thoughts, and constantly rustling high frequencies when listened to attentively evoke dissociative sensation, dissolving perception in the sonic field. However, everything as always depends on a listener himself. ~Zhelezobeton.
