Recorded for you, not for a record
Most backing tracks are programmed, looped or generated. These were played. George Benson came into the session to record play-along tracks for PlayAlongJazz, now PlayAlongTunes.com.
That means real time feel, real dynamics and the kind of phrasing you only get from musicians listening to each other. When you play along, you're responding to the same things a working band responds to.
Real world-class musicians. No AI. Only at PlayAlongTunes.com.
