jan garbarek - kind of new age sax (dont get hung up on the "new age" term, please) with lots and lots of middle-eastern and nothern european influences... good folky jazz...his albums expand the genre to new dimensions with NO improvisations. try "legend of the seven dreams" or "i took up the runes"
mahavishnu orchestra - great fusion jazz band formed by john mclaughlin.
miles davis - what can be said about this genius or which album should i point out? "kind of blue" is a classic, a must-have. "bitches brew" , "bags groove" , "birth of the cool."
aziza mustafa zadeh - probably the most amazing jazz vocalist alive (well, thats what i believe anyway). she's from azerbaijan and she always works with the greatest musicians, including omar hakim or...err say john patitucci. try her "dance of fire" album.
well i guess these are enough for a start. if these dont change your opinion, i guess nothing can.
