If you're going to cut records that clearly ape the sounds of Zeppelin, Pink Floyd, Sabbath and the Beatles you'd better be doing something interesting.

If you can take that interesting and knowingly quote parts directly from those bands you'd better be doing something really interesting.

Bigelf.
They're really really good. Like, i've heard this song before no I haven't and it's catchy and rolling.
You can't fault a band for showing this much ambition and truly 'going for it'.
Both the new record and the one before it are pretty awesome. Get passed the influences and you'll be rewarded.
At least buy them for your dad.

ps, that new Beyonce single is pretty killer. The "Single Ladies" one.
