Read the Book Louis Armstrong A life by Bergrand (?) was on Time s best seller list and is a jazz book wose prose and historyography is above all the others.Yes he created the INDIVIDUAL musician with his soloing.The best Jazz/Drug/Prison book is Sraight life by Art Pepper.Blue People by Leroi Jones in interesting too.But I'd say you'd need a list.Armtsrong and Bing Crosby created modern singing in 20's.Yould have to make list.Ellington,Armsrong,Charlie Parker.Miles,Elvis,Dylan,Beatles,Stones,Zepplin.Maybe the most polytheistic guy was Ray Charles who could sing and play in any bag.But it's hard to deny many of he above.Zappa was genius.As were Bernstein.......But you have to take the question in terms of idiom."Music" is just too broad.The one thing s in the Classical arena not many voices extend beyond Stravinsky in 1904.Maybe Bartok but I might not even have right century.
