Book excerpt: What does jazz mean 20 years into the 21st century? Has streaming culture rendered music literally meaningless, thanks to the removal of all context beyond the playlist? Are there any traditions left to explore? Has the destruction of the apprenticeship model (young musicians learning from their elders) changed the music irrevocably? Are any sounds off limits? How far out can you go and still call it jazz? Or should the term be retired? These questions, and many more, are answered in Ugly Beauty, as Phil Freeman digs through his own experiences and conversations with present-day players. Jazz has never seemed as vital as it does right now, and has a genuine role to play in 21st-century culture, particularly in the US and the UK.
