"- 'So by 1908 the public... called it 'blues'...' I don't know of any evidence that anyone was thinking there was a type of music they called 'blues' music before 1909. (What people called blues music, starting in about 1909, included songs that predated 1909.) Handy's 1926 book claims that the idea of blues music as a type of music was known in various states during the year 1910, but only arose shortly before 1910. The other evidence we have (Kid Love playing 'Easton Blues' in Texas in 1910, for instance) supports that book's claim."

<-- This quote is about the idea of quote "blues" music. We don't know of any examples of that from before 1909.
