A lot of singers/bands sound great on recording, but when you hear them live, it's suddenly a different story, and you cannot believe that they're out earning money with voices like theirs.
What are some of the live performances that you remember really throwing you off a particular band/artist?
For example, with Chinese singers nowdays, it's basically all lip synching and if it isn't, gosh, it's either background singers you hear instead, or it's just plain off-tune, flat, probably in the wrong key, pronunciation flying everywhere...
