When Queen started touring in the 70s, there were questions if (a) they could reproduce their studio recordings live and (b) would they use pre-recorded backing tracks? The early consensus was “no” and “they’d better not.” The thinking was that people were paying to hear a live band and not something that was recorded.
Backing tracks used to be consider verboten and generally uncool. How times have changed. Backing tracks in live performances are everywhere. But is that still cheating like in the old days?
