In addition to a slew of new original songs, the album includes several existing P&S songs that hadn't been released on CD yet (most all of which received some degree of remixing and/or re-recording), as well as a number of theme songs and other music we've done in association with other projects (including The Thrilling Adventure Hour, author John Scalzi, The Guild and more). Plus, it includes a six-track sampling of songlets from SoundBard, our upcoming RPG soundboard app. It also features cover art by xkcd creator Randall Munroe (and also art from Adam Koford), and musical guest appearances by the likes of Jonathan Coulton, The Doubleclicks, Mike Phirman, Dave Hill, Jim Boggia and many more.
