I've definitely experienced acts which are amazing in the studio, terrible on-stage. I do not speak of autotune-artists. Sometimes it is the fault of the audio engineers at the venue, and sometimes it is synthetic music that was born on a mixing board, rather than on a stool in front of a microphone.
