Here is a description of this material from the Bill Evans Webpages:
Between autumn 1989 -1994, a (hard copy) newsletter dedicated solely to the music and the life of Bill Evans was published by well-known Evans historian and bassist Win Hinkle. (Those who have appreciated Bill's work since that time may have seen references about Win and his published materials included in both the Peter Pettinger and Keith Shadwick books) "Letter From Evans" was available by subscription only back then, but now Win has made all twenty-six issues available online in .pdf files-- and it's all free!
During it's five-year run, LFE featured Evans news, album reviews, commentary, analysis, transcriptions and many exclusive interviews done mostly by Win with some folks you just might have heard of: Keith Jarrett, Marc Johnson, Steve Allen, Earl Zindars, Joe LaBarbera, Henry Mancini, Chuck Israels, Mundell Lowe, Jimmy Rowles, Denny Zeitlin and many others!
Some rare interviews with Bill himself from various sources appeared in LFE too, as did a number of nifty transcrptions of Evans solos -- many that were not available elsewhere. Just a few of those who contributed articles or reviews included musicians like Jack Reilly, Hal Galper, Kenny Werner, Richie Bierach, Evans archivist Ron Nethercutt and, in fact, yours truly (Jan Stevens).
For those Bill Evans fans and jazz listeners who haven't seen any issues of "Letter From Evans", you're in for quite a treat. They are all filled with loads of unique material-- and some related jazz reviews and comentaries from that time - that you just won't find anywhere else. Once again, the files of all issues are now free (though Win has mentioned at his blog that those who may wish to can contribute, just to help defray all the expense).
Obviously, if you're an Evans aficianado, or even a casual fan, this is big news. asdf
