Videmus
"This phase of the project focuses on the art song (other genres will follow) and delivers a searchable online database and printed book (release to follow) that organizes more than 2000 entries to help further the study of this neglected repertoire. The project will continue to evolve as new entries are created, and additional media & supporting materials are added in the near future for each entry. The database is organized and searchable by several fields e.g. composer, title of work, cycle, publisher, and poet. You can also search specifically for women composers, spirituals or search by pre-assigned stylistic periods. In addition, each record includes the key, range, date of composition, the presence of dialect, and notes about the composition such as dedications or first performances. If a work appears in more than one collection, citations are given to help researchers find any of the collections for a particular work."

Choral Music of Black Composers
Beyond Elijah Rock: The Non-Idiomatic Choral Music of Black Composers
"The following spreadsheet is a working list of the non-idiomatic choral music of black composers. In no way is it meant to be an exhaustive list. However, it serves to provide a starting point. Regular updates will be made. Non-idiomatic, as it relates to black composers, refers to the original concert music that is not part of the traditional idiomatic canon associated with black musicians. That canon includes spirituals, gospel, jazz, hip-hop, and rap among others. There will be pieces that may be based on spirituals or gospel tunes but are, at their core, original songs similar to ones that use chorale tunes in cantatas and popular songs parodied in Renaissance masses. This list does not include arrangements of existing material such as hymns or other folk songs. Available tabs at the bottom of the list are Full List, SATB, SSAA, TTBB, Other Voices, Unaccompanied, Accompanied, and Choral-Orchestral."

League of American Composers: Racial/Ethnic and Gender Diversity in the Orchestra Field
Racial/Ethnic and Gender Diversity in the Orchestra Field Forty Years of Fellowships: A Study of Orchestras' Efforts to Include African American and Latino Musicians Of and For the Community
"Both reports offer insights based on rigorous data and careful methodologies. Racial/Ethnic and Gender Diversity in the Orchestra Field uses longitudinal data – going back nearly 40 years in some cases – to identify trends and to ultimately establish a baseline of where we stand today. Forty Years of Fellowships also looks back – examining the efficacy of one of the field's most common strategies for addressing the homogeneity of the musicians who play on stage – while looking forward: Forty Years of Fellowships contains a number of recommendations that could be used to strengthen not only fellowship programs but diversity efforts of all kinds."

UbuWeb
"Founded in 1996, UbuWeb is a pirate shadow library consisting of hundreds of thousands of freely downloadable avant-garde artifacts. By the letter of the law, the site is questionable; we openly violate copyright norms and almost never ask for permission. Most everything on the site is pilfered, ripped, and swiped from other places, then reposted. We’ve never been sued—never even come close. UbuWeb functions on no money—we don’t take it, we don’t pay it, we don’t touch it; you’ll never find an advertisement, a logo, or a donation box. We’ve never applied for a grant or accepted a sponsorship; we remain happily unaffiliated, keeping us free and clean, allowing us to do what we want to do, the way we want to do it. Most important, UbuWeb has always been and will always be free and open to all: there are no memberships or passwords required. All labor is volunteered; our server space and bandwidth are donated by a likeminded group of intellectual custodians who believe in free access to knowledge. A gift economy of plentitude with a strong emphasis on global education, UbuWeb is visited daily by tens of thousands of people from every continent. We’re on numerous syllabuses, ranging from those for kindergarteners studying pattern poetry to those for postgraduates listening to hours of Jacques Lacan’s Séminaires. When the site goes down from time to time, as most sites do, we’re inundated by emails from panicked faculty wondering how they are going to teach their courses that week. "The site is filled with the detritus and ephemera of great artists better known for other things—the music of Jean Dubuffet, the poetry of Dan Graham, the hip-hop of Jean-Michel Basquiat, the punk rock of Martin Kippenberger, the films of John Lennon, the radio plays of Ulrike Meinhof, the symphonies of Hanne Darboven, the country music of Julian Schnabel—most of which were originally put out in tiny editions, were critically ignored, and quickly vanished. However, the web provides the perfect place to restage these works. With video, sound, and text remaining more faithful to the original experience than, say, painting or sculpture, Ubu proposes a different sort of revisionist art history based on the peripheries of artistic production rather than on the perceived, hyped, or market-based center."
