A genre originating in 80s England, now international. Defined by highly distorted guitars, and vocals, usually high-and-breathless or low in the mix, sometimes absent.
A psychedelic style, but not "trippy" psychedelic, more a dreamy, distant feel.
Pioneeered by My Bloody Valentine, but few bands actually sound like them anymore.
Loud guitars and quiet vocals is a usual dynamic.
Shoegaze is defined by a certain guitar sound, so electronic bands such as M83would NOT be considered shoegaze, but could fit into the related genre of dreampop
Shoegaze comes from the use of distortion pedals to achieve a dreamy/psychedelic sound
