I became a fan of rock music because of AC/DC and I nearly went deaf listening to the "If you want blood" live album on my Walkman as a kid. Back in Black was the first vinyl AC/DC album I owned, as I borrowed the others from my older brother. It took my breath away back then and it still has the same effect now. I am torn between this, Let there be rock and Highway to Hell as to which is the ultimate of thier albums, guess it depends on my mood. All 3 live in my car some 25-30 years after thier release, testament to their lasting appeal. I would advise you buy all 3 along with the aformentioned If you want blood and enjoy bar brawling, womanising, gutsy rock n roll at its absolute finest. As for Back in Black itself, play very loud, have your air guitar tuned and ask yourself if any rock album since has bettered this. AC/DC at thier finest and sadly the last truly great album they recorded.
