Gearing up for the "Book of Souls" release will be a retrospective CD of SC3 music over the years, called "Path of Most Resistance", which will feature selections from the previous albums and some rare tracks and video. Not necessarily essential for hardcore fans (except for the bonus material), but it will definitely be useful to introduce new listeners to the daunting output of the SC3 (finally an answer to "which one should I start with?"). It's also going to be a good promotion tool on the cusp of the SC3 next mega opus.
