I used that line in the 'live albums' thread. In that context I meant that it made me realise that music wasn't just the pre-packaged 'same every time' item that i heard on the top 40 every Tuesday lunchtime, it was alive, fluid, ever changing, never the same twice. This revelation made me 'get' why people went to see bands live over and again, you may hear the same songs, but the experience is never the same, this was part of my growing up, and truly did change my outlook on life.
