sorry if this seems like a stupid question to ask, but you know how bands (UVERworld, HIGH and MIGHTY COLOR, ORANGE RANGE, etc..) all play instruments during live performances (like on POPJAM, Music Station, etc..), are they actually playing the instruments or is it just the studio recorded version playing in the background? the same goes for solo artists, like younha (who plays the piano) and just any jpop artist that plays a certain instrument.
