My friend is a huge Beatles fan and he forced me to listen to Helter Skelter a few weeks ago. I didn't know they rocked that hard :O, I had only ever heard stuff like I Wanna Hold Your Hand etc.
Me and my friends used to listen to this while driving around all the time, it really is the an underrated album. It's The Beatles at their barest and the songs are very grounded...nothing too out there as on past albums. I recommend it as a great album, but not the greatest
