James Brown had that vertical integration once he hit his stride in the 1960’s.
It wasn’t uncommon for him to take the band in for a late night studio session (after a 3 hr show). The song would be recorded and mixed on the fly. Then a copy would be sent to his vinyl pressing plant, which could turn the physical copies around in a day. At the same time, the radio stations he owned in the Augusta GA, area would start playing the latest cut. Just in time for it to hit stores and be available for purchase.
