This week's "Sonic" Moment of Calm is more a moment of magic. That moment, when walking along the street, you hear the sound of music and realise (with delight) it's not a recording, but someone playing, struggling with, and mastering a real living instrument. It doesn't matter whether they're a genius or a beginner, it's the act of making music that counts. RNZ Concert host Bryan Crump was in the right place at the right time, and thought you might like to be too.
