“First the tapes have to be baked. We bake them at a low temperature for eight or nine hours,” says musician and sound engineer Ted Orr. He is sitting at the console where he has been digitizing tapes recorded at Woodstock’s Creative Music Studio (CMS, and actually it was in West Hurley, the old Oehler’s Lodge, now the New York Conservatory for the Arts) in the 1970s and 1980s, when Don Cherry, Cecil Taylor, Anthony Braxton, Jimmy Guiffre, Nana Vasconcelos, and many other avant jazz greats collaborated with musicians of other genres to create new kinds of music.
