Overall, Backtracks is not quite the treasure trove that fans might have been craving all these years, and it might have been a better idea to offer complete remastered CDs of AC/DC's first four Australian albums instead of the single-CD mishmash, or even dig a little deeper into the live/studio vaults. That said, in spite of some bumps along the way, it's still a very fun seven or eight hour trip.
If you find it impressive how AC/DC have spun three chords into a 30-year career, then you'll enjoy what they can do with a boxset: Backtracks comes with three CDs, two DVDs, all packaged inside a recession-friendly amplifier. [Jan 2010, p. 103]
Nor will any but the most dedicated fan have any need for the live cuts, given the extraordinary amount of live AC/DC material already available.
