They Might Be Giants next release is BOOK which is indeed an book, but also a vinyl record, CD and cassette. Here's more:
They Might Be Giants’ brand new project is a deluxe set: A 144-page cloth-bound hardcover art book of full-color photography, as well as original TMBG lyrics graphically set in the style of poetry concrete by world-famous designer Paul Sahre on an IBM Selectric typewriter from the early ‘70s. The featured lyrics are selections from BOOK, a forthcoming EP, My Murdered Remains, and I Like Fun. Inside every book of BOOK there is a copy of the musical album BOOK on an indestructible compact disc, and everyone who orders the book of BOOK will get an instantaneous download on release day. Both the fancy WAV format and the practical MP3 format will be available to you.
