I'd like to thank a few people for great help and encouragment in making Jack DeJohnette discography. Without them it wouldn't exist in so rich form as it is now. Here THEY are:

D.D. Robert Jackson
DDJackson@worldnet.att.net (for his continuous support and big amount of useful infomations, despite having so little time as a musician for such things like WWW discographies)
Look for his first solo album called D. D. Jackson "Peace-Song" (Justin Time) featuring David Murray!!!
He isssued new CD recently and his fame grows with every article. Sometimes You can meet "him" on news group devoted to jazz music: rec.music.bluenote where he talks about new projects and tour dates.
Now he's got brand new Web page with all info. Check it out:
