Slowcore

Slowcore, also known as sadcore, is a subgenre of indie rock characterised by its subdued tempos, minimalist instrumentation, and sombre vocal performances. Slowcore's influences are diverse, involving various other genres, including folk rock, alternative rock, and dream pop. As a result of these contrasting stylistic directions, there is no definitive characterisation of the genre.

"Svefn-g-englar" is a song by the Icelandic post-rock band Sigur Rós, from their second album, Ágætis byrjun.
