I've heard it too and its a really good album. David's voice has obviously changed over the years, but he's pretty good on this album. Definitely a great mix of old/new style Whitesnake. A few cracking tracks such as Tell Me How, All Out of Luck, Whipping Boy Blues, My Evil Ways and the brilliant Forevermore.
I wish people would give him, and the band a chance. Yes his voice is different, and yes Moody/Marsden aren't there anymore. They still make cracking hard rock with a blues influence!
