KJK is an inclusive community that was established on 17 March 2004 in Kemayoran Jakarta. The founder, Beben, held rehearsals and open mike events every Wednesday with a few close friends at his home. At that time, jazz was considered as music for the upper social class, but Kemayoran was in a lower medium class neighborhood at that time. All the activities were held in Kemayoran until 2019: free weekly workshops on Thursday and free monthly events all under the creed of “Jazz for all”, cherished by Beben who sees Jazz as means of building friendship, comradeship and companionship. KJK also has an educational mission as Beben Jazz Music Courses offer music classes open for all publics. KJK also realizes that many people, especially young people, want to enjoy jazz music, follow their passion and make their living out of this passion.
