When I was an errand boy and tape dubber at Sigma NYC (1981-83 summers),
the commercial business was transitioning away from a squad of crack
studio musicians showing up, getting a chart and cutting a commercial in
3 hours to where one guy showed up with a Synclavier and dumped 8 tracks
onto tape and then a singer showed up and a voice-over guy showed up and
they cut a worse commercial but in half the time. Nowadays, it's a guy at
home with a MIDI rig cutting even worse commercials but for a fraction of
the cost. That's a large part of what killed off the big studio business
in NY -- the agencies took most of their production in-house and
musicians' union rates got to where no one could afford big sessions with
large ensembles anymore. Plus, the um "talent" pool has gotten very
brackish in recent generations of "musicians."
