This talk presents the basic tools of audio signal analysis for music information retrieval, and discusses the prospects for their useful application in jazz music collections. This work is part of a project led by the Center for Jazz Studies to build a collaborative online resource for information on jazz recordings known as J-DISC. Music Information Retrieval (MIR) is a young field that applies tools from machine learning and signal processing to obtain information about musical items.
In the 20th Century, improvisation in the contemporary arts has served as a symbol of new models of social organization that foreground agency, history, memory, identity, personality, freedom, embodiment, cultural difference and self-determination.

In 1974, Anthony Braxton was considered a radical among radicals. This was true not least for his distinctive embrace of post-war European avant-garde composition, then assumed to be particularly uncongenial to the average listener's taste.
"We are in the transhuman age," declares composer Pauline Oliveros, referring to the extension of human capabilities through technology. Oliveros tells how her own early improvisations with tape recording and editing anticipated many current creative uses of sound technology, and asks how further advances will bring new tools to experiment with and new realms to explore.
In "'Come on in North Side, you're just in time': Musical-Verbal Performance and the Negotiation of Ethnically Segregated Social Space," Scruggs explores the ways that tenor saxophonist Von Freeman used both music and speech to create a sense of community and shared tradition through his performances at Chicago's Enterprise Lounge during the 1970s and 1980s.
Lewis notes that race has been "e-raced" in studies of free jazz in Europe and America, which he finds surprising given the music's emancipatory thrust. He investigates a recurrent ambivalence about the African-American contribution to free jazz, at once taking experimental cues from it, yet denying that it is capable of evolving or progressing itself. After uncovering coded assumptions about race, ethnicity, and class behind this ambivalence, Lewis explores the possibilities for artists to transcend, transgress, and perhaps even erase boundaries.
Nicholls argues that the way artistic projects are represented depends at least in part upon the willingness of critics to look beyond musical sounds alone and take notice of issues of identity and social positioning-their own and that of the artists they evaluate. To illustrate this point, she discusses the varying reception of John Coltrane, whose stature gave him a platform to resist and redress the negative judgments his experimental work received.
