On the CDBaby page for this CD, all Paul really has to say about it is, "Writing the music for this CD gave me peace, I hope it gives you peace listening to it."
In my case, it succeeded. Paul's brand of instrumental rock has been compared to the likes of Mogwai and Pink Floyd, which puts it pretty far away from my usual instrumental rock diet of Joe Satriani and the like. Not to belittle any instrumental prowess Paul may possess, he forgoes guitar pyrotechnics and distortion for drifting melodic ideas and washes of sound. That's not to call it boring by any means though. CDBaby has it categorized under soundtrack, and that's not much of a stretch--played straight through, the music has an abstract feeling of a journey through emotions from the lighter beginning of the CD, "Into the Center," to a heavier, more active crescendo later in the disc on "Sid Anmchadna."
If your only interest in instrumental music is virtuosity, you may as well stay away from this. Otherwise, Paul has composed an interesting, enjoyable disc either as background for whatever else you're doing or to just turn the lights off and let the waves of sound crash over you.
