There was a German startup called Bleecker Street [1] about a decade ago that did exactly that. They toured with artists like Chris Rea, Simple Minds, and Mark Knopfler, tapping directly into the FOH desk at each venue. They would mix the audio live, even adding the ambient noise of the crowd to capture the live feeling.

Right after the show, you could buy fancy looking USB sticks, designed with unique elements of the artists, pre-loaded with the recording of the set you had just heard.

I still have a guitar-shaped USB stick from a Mark Knopfler show at a small venue in a tiny town in southern Germany. Honestly, it’s a far better souvenir than any picture I could have taken.
