Slint - Spiderland - 1991

Spiderland is the second studio album by the American post-rock band Slint, released on March 27, 1991 on Touch and Go. Featuring dramatically alternating dynamics and vocals ranging from spoken word to shouting, the album contains narrative lyrics that emphasize alienation. Spiderland was Slint's first release on Touch and Go, and the group's last record.

prog-rock so humble people had to invent the term "post-rock" to classify it

Alcest - Ecailles De Lune - 2010

Alcest is a musical project born in Bagnols-sur-Cèze, France. It began in 1999 with three members – Neige, Aegnor and Argoth. This band released a demo of black metal songs in 2001. Shortly after, Aegnor and Argoth left the band, leaving Neige as the sole member. This marked a change in style, as Alcest's subsequent releases have more often been described as shoegaze.

this reminds me of sigur ros but that is probably only because it is shoegazy/post-rocky and in a different language
