There's an excellent, loong interview on Archinect with Kenneth Goldsmith, the artist, poet, dj, theory karaokeist [?], professor, and web developer behind the incomparable UbuWeb.
Ubu began with just texts, and as collections and formats and partners came their way, it's expanded into other media: sound, performance documentation, artist film and experimental video. The focus remains resolutely on the undeservedly inaccessable and out of print/circulation.
Goldsmith: "My only regret though is that there aren't fifteen or twenty UbuWebs." They talk about theater, dance, and architecture Ubus, but I confess, I have a hard time seeing how those might come together as well as Ubu's collection of conceptual/concrete poetry. Could happen, though. Anyone have some unlimited bandwidth and server space? There may be a MacArthur in it for you.
