“Improvisation is the basis of learning to play a musical instrument. But what usually happens? You decide you want a certain instrument. You buy the instrument and then think to yourself, ‘I’ll go and find a teacher, and who knows, in seven or eight years’ time I might be able to play this thing.’ And in that way you miss a mass of important musical experience…a person’s own investigation of an instrument–his exploration of it–is totally valid.” –Drummer John Stevens
