Charles Bernstein hosted the "Linebreak" radio series, which, in digital form, was originally presented in RealAudio format and then converted to mp3. (MP3 of course is PennSound's and many others' preferred format - downloadable, nonproprietary, free.)
In the spring of 1995, in New York, Charles conducted an interview with Susan Howe that has all along been my favorite of the Linebreak shows. We've now segmented it - by topic - and created what amounts to a table of contents. Above is a snapshot from the freshly revised Susan Howe PennSound page.
