This week, a conversation with Ted Libbey, author of The NPR Listener's Encyclopedia of Classical Music. His book has broken new ground in publishing by having a companion website where readers can listen to full length examples of musical works cross-referenced in the book. Tom Dinardo explains how he spent six years trying to organize a performance of a work for organ by legendary Hollywood composer David Raksin. Susan Lewis explores Betsy Ross House. And Jason Peifer previews the world premiere of Some Men, a Terrence McNally play set to open at the Philadelphia Theatre Company.
