Satchography! Whether or not you agree with Ken Burns (and many others) that Louis Armstrong is the font of jazz and modern American music, you have to appreciate the effort and care that have gone into this site. Fans, researchers, and casual listeners can use the site to access comprehensive information on Armstrong's recordings, sessions, and the composers. These are collected in seven sections which chart the course of Armstrong's career. Each section begins with an introduction and lists recording dates and song titles with a link to session details, which include composer, record label, and release number of first issue, the musicians featured, and CDs (or, in some cases, vinyl LP) where the song can be found. Pops's appearances on television, radio, and film are also noted, but detailed information is not yet available. The site is intended to serve as a working compendium, and suggestions, new discoveries, and comments are welcome.
