due to lastfm spotify and deezer i do much more discovering than i used to... not so much single artists at the moment, rather "projects", one project is violin players, jenny scheinman, mark feldman, carla kilhstedt, leroy jenkins... another one is california saxophone players earl anderza, jimmy woods, hadley caliman, teddy edwards, daniel jackson, the guys on nimbus west... i have also started listening to "hyped jazz musicians of today" recently, a group of people i had neglected for a few years, played matana roberts, lionel loueke, mahanthappa/iyer...; also quite a bit of discovering in the esp disk and tzadik catalogs... then i also developed an interest in "piano dominated" jazz which i had avoided for quite some time, mostly along two lines, the beboppers like bud powell, al haig, duke jordan, dodo marmarosa and through the french pianists, michel graillier, georges arvanitas, martial solal, also alain jean marie,... (which actually also got me started with european jazz more seriously for the first time...)
single artists i am most interested in at the moment are mal waldron and sonny simmons... (but both on and off for quite some time)
fifteen years into listening to jazz and i believe i rarely discovered more than at the moment...
