oddly enough Rolling Stone put out a book titled "Book Off The Beats" which is very good and which has every article that was in the mag over the years including some new articles. There are a few sections which cover the correlation between jazz/be-bop and the writing of the beats. There is also the Antholgy of Jazz Poetry which is all pomes but could prove to be good reference material, icludes some work of Kerouac, Bob Kaufman, Ferlinghetti, et al, on composers and their sounds directly. Some good material in it. That should give you a good start.
