The fact that The Pack A.D. don't have more traction with the media borders on the criminal. Sadly, I think that it is a Canadian thing - if they were based on the East or West coast in the US, they would have had a larger footprint.
I stumbled onto one of their songs from their second album ('Funeral Mixtape')on the show 'Being Human' (The US version). From that I got sucked into their first two albums, and was well rewarded. Their earlier material was a nice, blues-and-grunge breath of fresh air.
'Unpersons' is The Pack A.D.'s 4th album, and is even better. They retain their rocking-grunge-punk-blues sensibilities, but mix in more complex moods and post-punk instrumentation. Think Johnny Cash-meets-Frank Black-meets-Patti Smith, but even that is a grossly facile description. Any comparison will come up short - The Pack A.D. REALLY have a unique sound, one that has been improving over the course of their body of work.
The short version of this review - 'Unpersons' is their fourth album, and their best yet. GREAT stuff - buy it!
