SE_D0124/FRQ-TITS.S3M

 Mistigram: Sorry to mislead everyone -- the song's filename is an acronym for "Trapped in the Subconscious."  This is a Scream Tracker S3M tracker music file composed by Freaq in 1994, played, interpreted and visualised by Eto's SEPLAY MS-DOS executable traditionally bundled with Sonic Equinox releases.  Both the song and the player are included in the new SE_D0124 music disk, rounding up a large quantity of unreleased computer music compositions dating to the mid-'90s.  You can download it via mistigris.org/newmedia or if you prefer you can enjoy curated selections via mistfunk.bandcamp.com
