2024-DEC-10 Info: Did you check out MC101? Want to write a "Space" themed song with SWC088? Or do you want to provide samples for "Community Scramble 2025"?
You can get access to STEMS from a cover version of "Meshuggah - Bleed", created by guitarist Sarah Longfield. The STEMS are distributed as "pay what you want" via Bandcamp. According to the Youtube video outro, the tracks are both available in DI and "amped" form. Although (from listening to the preview streams) most of the tracks are processed already, not "stripped clean". Still interesting for learning purposes, and testing guitar amp settings.
They are All Right Reserved (C), a pity because we could otherwise work on remixes and stuff (it would work as promotion for them D:), still, pretty interesting! I know other stems sites but I don't know if they are fully legal, will check them out and see if I can post them here.
It's still great for private stuff (training, experimenting, learning).
There are indeed plenty of pages out there for that purpose. But none of that material is "suitable" for the Challenges. I just saw this today out of pure change and thought "worth sharing".
