Context Modern jazz music is very diverse and difficult to classify. Nonetheless, when it comes down to preferences, every jazz listener will probably select his/her group of musicians to follow. I believe that good record labels are doing awesome job at "curating" jazz records and shaping the musicians (either directly, like Manfred Eicher, or indirectly, by de-selecting opportunities that do not fit his/her interest profile). ECM Records is a proud holder of Jazz Label of the year for many years in the row. I think it would be very interesting for jazz-loving Kagglers to follow the steps of Manfred Eicher in shaping the musician line-up and creating unique world-wide famous "ECM-sound".

Acknowledgements We owe a ton to the diligent collectors and people behind Jazz Discography Project (Nobuaki Togashi, Kohji 'Shaolin' Matsubayashi , Masayuki Hatta) Inspiration What communities of musicians (people who collaborate together) exist on ECM? How did they come about? How does Manfred balance adding new communities(through audition), vs. adding new members to existing communities (primarily as referrals)? What instrument combinations are most common on ECM (piano, drums, base, of course, but still). When did the transition to electronics happen for ECM? What albums had significant influence? Pick your favorite record and see how it fits into ECM's journey for perfect sound!
