Love Mystery! In fact I reviewed two of their albums in my journal, one of which ("The world is a game") also gets on my best of 2012 list. St-Pere is a real focal point for the band, and the vocals of Benoit David just totally complement his style. I think Mystery should be a lot better known than they are, and hopefully they will be before too long.
I can recommend "One among the living", although to be fair that and the new one are all I've had the time to listen to. I have little doubt that the previous four albums are just as good though.
