No kidding. Consider the possibility that this was the first avenue I pursued and was nevertheless stymied in my efforts.
One of the bands only sells vinyl outside of Spotify (I have the record on Vinyl, but the process of digitizing it is similar to recording straight from Spotify but harder), and the other band is based in Mexico and doesn’t have a digital marketplace. In both cases I’ve literally emailed the bands offering to overpay for raw digital files but haven’t heard back yet. I am seriously considering flying to Guadalajara to catch them live and pick up a CD there. They don’t really tour in the US north of Texas.
