just proves what's necessary

She's playing a really cheap and lousy guitar in an open tuning and clearly doesn't know the "correct" way to play a guitar... but what wonderful music!  Just goes to prove that the most important part of making music is in the heart and soul of the player... technique is secondary (although she clearly has great technique even if it is "wrong") and the quality of the instrument is secondary (even though with a better guitar she would have sounded that much better).

So... the lesson for me is, "play, play, play... and then play some more.  just make music and don't worry about the other things."
