Well, Scott, if I were you, I wouldn't go and see ANY pop music show by an artist under 30. Tapes, sequencing and loops are a fundamental part of any big tour, these days. I even met a young(-ish) man the other day who used to sing under the stage for Toto, back in the day. Whenever the lead singer's voice was shot, they flew him into the mix!! Multi-million dollar tours cannot afford to have a bad night for ANY reason. Do you think Destiny's Child (or ANY dance artist) can dance THAT vigorously, and still sing well?
And don't get me started about country music, the most Beat Dectective'd, Auto-Tuned music on the planet!
And finally, lest we all forget, an arranger is nothing BUT fakery........ only the parts you play yourself have any more musical honesty than Milli Vanilli.
