Neil Young wants to start a revolution against the MP3, against the CD, poorly made vinyl, and poor audio quality in general. He wants people to hear the music the way it was made. So at SXSW, Young introduced Pono. In Hawaiian, the word means righteous or goodness. For the world of sound it’s an audio player that Young says he’s been working on for 2 1/2 years, one that’s capable of playing music at the same quality at which it was recorded.
