{"value"=>"<p>This series contains paperwork documenting the working relationship between 128 different musicians/recording artists and Columbia records or Teo Macero's M. Productions. The length and products of the relationship range from a one-day failed audition to, in the case of Miles Davis, a decades-long partnership yielding over 30 album releases.</p> <p>Within folders, the papers are divided into roughly four categories. The first, correspondence, consists of inter-office memos, letters to and from the recording artists or others, contracts, invoices, purchase orders, and hand-written notes. The second category, datasheets, refers to any evidence of the production of sound recordings, including studio tape and session logs, job sheets, notes on tape content, mastering information, and album cover copy. The third category, promotional material, refers to handbills, advertising copy and proofs, or other publications produced by Columbia's promotions department. The fourth category, clippings, refers to newspaper and magazine cutouts or issues. Some folders also contain sheet music related to the recording project in question. \"General\" folders at the end of each artist's section often contain important material which is not associated with a particular project, such as contracts, correspondence or tour itineraries; a general file at the end of the series contains items not associated with a particular artist. Further notes on particular artists appear under their names.</p>"}
