An absolutely fucking fantastic list of silent musical compositions! Check out Sleepify album by Vulfpeck.
It should also include “The Experience Of Silence” from the album “The Experience Of Silence” by Two Witches and “Minuutin hiljaisuus” from the album “Sisäinen solarium” Ismo Alangon Säätiö (I’ll add them later).
I’m sitting next to the Record Singers LP cover which has never included an album inside.. I’m not sure if the eight songs listed on its back cover count as silent compositions. The songs on this record are radically absent compositions. I listed it on the Discogs site.
