I warily stepped into this CD — it being recommended by my brother, who had also recommended The Vines, Jet, and Green Day. None of the last 3 bands does anything for me. I grew up with Zeppelin, Deep Purple, Black Sabbath, and AC/DC, and have yet to find anything comparable in the last 25 years (Rush’s Vapor Trails is excellent however). This time, I struck gold. This CD is fantastic. I hesitate giving it 5 stars, because it is pretty basic. But I hold 5 stars to gems such as Machine Head or LZ 1-4. Someone commented that the lyrics are a joke – but listen to the lyrics of Whole Lotta Love. Lyrics are important, but the songs matter most. All of the songs on this CD are good – and most are great. If they can develop,like Zeppelin did (but Purple never did), they could turn out to be a phenom. However, they could turn out to be a one-CD wonder. My usual question for rating a CD is – will I listen to this 5 years from now?? I’m pretty sure I will. Rock and roll needs a good comeback amongst all the garbage that is out there. Please let rap die and rock flourish.
