The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at the Trope Launch Pad.
Seems like one for TropesThatWillNeverHappen.Too Subjective. Aside from the likelyhood it would become a list of every band that had a concert someone liked, I've seen vicious arguments about whether Bono's freestyling on U2 song lyrics is musical genius or grating. (There's a 16 minute live version of "Bad" from one of their East Rutherford concerts that is pure musical rapture.)

Most common for music but could also apply to radio and TV shows that also run as theater plays.
Do we have a trope for a group that's considered better in their live performances than in the studio?
