The New York-based vocalist and producer knotted has quite a few releases on Nina. Some of them experiment with sound collages, voice memos, and field recordings, while others veer into more ambient territory. “sigh sigh,” though, is a piercing, lo-fi guitar song that mostly just makes do with a brooding, grief-stricken voice and a simple-yet-effective guitar melody. Towards the end, however, peculiar digitalized sounds enter the track, giving the whole thing a resolution that is both fried and also a little triumphant. The song is taken off of knotted’s brand new record the fog grew faint, which is available for listening on Nina right now.
