I've been listening to my newly acquired CD of that New Zealand band The Datsuns for the last week or two. I have to say that for the most part IT ROCKS! The only song I feel is much weaker that the others is track two, "MF From Hell." Apart from that track, if you like the band Deep Purple, lots of dirty, raspy Hammond organ work and guitars, then you'll probably like The Datsuns.
There, that's my critique of them. Buy it or not, as you see fit.
