Yesterday, one day ago is the first EP by German Neocities user Strata. The EP features samples of a number of audio tracks from Willy Wonka & the Chocolate Factory, Twin Peaks, and Synthetic Substitution, along with 10 other samples (13 in total) just to name a few. In all, the small album has 8 original music tracks in it, lasting just over 20 minutes.
The EP was published as a free download via Strata's website on 2018-04-07.
For the README file of the download (LinerNotes.txt), Strata writes that all of the tracks were created, mixed, and finished in Ableton Live 9, along with making a tank you section;
THANK YOU ========= First, I'd like to thank you, dear listener, for listening to this heap of shit. I'd also like OwlMan ... 1) For giving the valuable feedback I did not want to hear during the refinement of these tracks. 2) For hosting the Opus files for web-based listening.A whole year later on 2019-04-11, Strata published a fair well letter from the host (Strata leaves the host), on the webpage, they link to a previously unseen track that they made, Running High '99, an "unfinished, and probably mixed poorly" that its title is a reference to the first opening track of Yesterday, one day ago, that being Running Low '98.
