I voted artist but should've voted genre. Something like jazz where the compositions change every night, where different personnel might be there... I'm only really interested in one studio take--whichever one they decided to make the master--but I can listen to tons of different live nights of the same playlist, especially for someone like Miles who would totally transform a song over and over.

But most music I couldn't care less about a recording of a live performance. Like I wanna track down a bootleg just to hear Nas yell extra loud into the microphone for the audience? Or hear Radiohead play the song exactly the way it is on the album but with shittier acoustics?
