This daily jazz calendar is published annually by "Company Co.", a publisher that brings the richness and vastness of the world of sound—including jazz, avant-garde, contemporary, and classical music—to the world through various music books. It is designed to introduce people to various styles of jazz, from famous to minor recordings, transcending time and national borders, with the restriction that each recording date features a work recorded on that date, and each artist's leader work is limited to one per artist. From ragtime to swing, Dixieland, modern, fusion, jazz-funk, and free jazz. We invite you to spend 2026 with an all-encompassing disc guide that will make you want to search for and listen to records and CDs on the internet, one by one, each day. Even in our store, our day begins by checking if we can play the record featured on that day.
