The second edition (2019) updates and adds to the original (2013) by Dr. Seth Greenberg.
Over 10 years of comprehensive research went into writing Billy Bean: The Life and Music of a Jazz Guitar Legend.
For the person interested in only the biography (i.e., without the catalog of Bean's autograph manuscripts), the abridged edition is best..
The book is divided into two volumes. Volume 1 contains all of the biographical and musical analyses. Volume 2 presents all of Bean's autographed manuscripts given to Greenberg in 2007. Within these manuscripts are lessons taken from the late-jazz guru Dennis Sandole, Bean's transcriptions and arrangements of pieces from the standard jazz and classical repertoire, and a several of Bean's original compositions. Each autograph manuscript has a corresponding transcription to clarify the many ambiguities presented by the original autographs. (550 total pages)
